How to Identify Authentic Akan Gold Weights: A Collector’s Guide

Akan gold weights are small cast brass and bronze objects, made by the Akan peoples of present-day Ghana and Côte d'Ivoire to measure gold dust, the principal medium of exchange in the Akan economy from the 15th century until British colonial currency reform in the late 19th century. They are one of the best-documented and most tightly typed object categories in West African art, and a serious collector can read each piece against a clear framework: casting method, surface, mass in grams, typology, subject and provenance.

This guide explains what Akan gold weights are, how they were made, how the tradition evolved from geometric to figurative forms, the four main object categories you will encounter on the market, how to read subjects and proverbs, how to authenticate a piece, and what role provenance — particularly the Egon Guenther and Hans Himmelheber collections — plays in current valuation. It is written for collectors and first-time buyers who want to assess an Asante weight with discipline rather than optimism.

What Akan Gold Weights Are

Akan gold weights, known in Twi as abrammuo (singular) or abremmuo / mrammou (plural; multiple spellings appear in the trade), are small brass and bronze weights cast by the lost-wax method. They were used to measure gold dust, which served as the principal medium of exchange in the Akan economy from at least the 15th century until the introduction of British colonial currency in the late 19th century.

The Akan grouping covers the Ashanti (Asante), Fante, Baule, Anyi, Brong, Kwawu and several smaller related peoples. The Ashanti kingdom, centred on Kumasi, was the dominant political and economic power during the classical period of figurative weights and is the group most often named on surviving pieces. "Ashanti gold weights" and "Akan gold weights" are therefore used more or less interchangeably in the trade, though "Akan" is technically the broader term. Pieces from the Ghana–Côte d'Ivoire border zone are often described as Asante / Baule, since the same tradition extends across the cultural and linguistic boundary.

A typical single weight is between 1 and 10 centimetres across and weighs between a gram and several tens of grams. Single figurative pieces in the European market today commonly range from around 19 g to over 50 g; mixed groups and complete weighing sets run from a total of around 60 g for a small group to nearly 200 g for an eleven-piece collection or 100 g+ for a seven-piece set with scale and gold-dust container.

Akan weights sit within a broader corpus of West African brass and bronze. Collectors often build outward from gold weights into wider African tribal art and ethnographic sculpture, where similar lost-wax casting traditions appear in figural work and ritual objects.

The Six Checks Framework

Before looking at typology or subject in detail, work through the same six checks on every piece you are considering. No single check is definitive on its own. A period weight passes all six, or at least the first five with an honest gap at six. A weight that fails on the first two rarely becomes trustworthy on the others.

The Four Object Categories You Will Encounter

Four distinct kinds of Akan brass material appear on the market, and confusing them is one of the most common mistakes new buyers make. They have different uses, different prices, and different things to check.

A serious collection should be able to identify which of the four it holds piece by piece. The descriptions on each item should make this distinction clear; if they don't, ask.

Figurative Weights: Reading the Subjects

Figurative weights emerged in quantity from the early 18th century onward and reached their classical expression through the 19th century. Gold-trade wealth, Ashanti court patronage, and specialist casters working in Kumasi and other regional centres drove a golden age of small-bronze production. The figurative repertoire covers almost every aspect of Akan life: animals, human figures, weapons, regalia, tools, plants, domestic objects, proverb scenes and abstract forms.

Most figurative Akan weights are not simple depictions. They are often visual shorthand for specific proverbs, and two collectors looking at the same "bird" weight may be looking at very different meanings depending on posture and context. A few frequently encountered examples:

• Sankofa bird (head turned backward). "Go back and fetch it." A widely reproduced form.
• Two-headed crocodile sharing one stomach. A reflection on the futility of internal conflict.
• Mudfish swallowing a crocodile. "It is the mudfish that swallows the crocodile" — unexpected reversal and the power of the seemingly weak.
• Hornbill. Wisdom and certain chiefly prerogatives.
• Chameleon. "The chameleon walks carefully in a strange land." Caution, discretion.
• Narrative compositions of figures with animals, often referring to Akan proverbs and social relationships.
• Anthropomorphic forms — highly stylised human or human-derived figures used to convey ideas of balance, ethics, authority and social order.
• Mask and head forms. Small sculpted heads and mask-form goldweights, of the type discussed in Angela Fisher's Africa Adorned, expressing rank, ancestral presence and spiritual protection.

These are not uniformly fixed meanings. The same form can carry different proverb associations in different Akan subgroups and periods. Attributing a single proverb to a weight confidently usually requires comparative references; at minimum, it should be flagged as an interpretation rather than a certainty.

A small but recognisable subgroup of figurative weights retains its original leather backing: a documented functional feature that provided stability and protection during use, while also carrying symbolic significance related to the handling of gold dust. Where present, the leather should be original rather than later-applied.

Geometric Weights and Mixed Study Groups

Geometric weights are the earliest and longest-running part of the Akan gold-weight tradition, produced from roughly the 15th century through the 19th century, with some continuation alongside the figurative series into the early 20th. They are non-representational: cubes, cylinders, truncated pyramids, stepped forms, discs, bars and composite blocks, decorated with stamped or incised patterns including parallel lines, crosshatching, zigzags, dots, spirals and radial fields.

They were the everyday working weights of most transactions and represent the majority of surviving Akan weight material. In the European market they are often under-priced relative to figurative weights, which makes them one of the better entry points to the field for a working collection.

Mixed study groups are particularly useful for buyers who want both halves of the typology in a single coherent assemblage. An eleven-piece abremmuo collection containing both figurative examples (such as chair and vessel forms) and geometric types is a single acquisition that demonstrates the dual aesthetic and symbolic vocabulary characteristic of Akan mercantile culture.

Complete Weighing Sets

A complete Akan merchant's set — famfam or nsania — comprises:

• A balance scale (small, of iron or brass, suspended by cords) with suspension pans
• A graduated set of weights (brass and copper-alloy, geometric and sometimes figurative)
• A brass gold-dust container (often a kuduo ceremonial vessel, or in chiefly contexts a decorated forowa)
• A scoop for transferring gold dust
• A sieve for cleaning the dust

Complete original groupings are increasingly scarce on the market, because the components were often dispersed once the system fell out of working use. A surviving set with scale, pans and container has documentary value in addition to its decorative interest, and typically anchors a collection. When evaluating one, look for:

• Consistent surface and alloy colour across the components (suggesting they travelled together)
• Coherent range of masses among the weights (rather than random gram values)
• A balance scale with intact suspension cords, or replacements that are openly disclosed
• A container with patina consistent with the weights themselves

Mixed-period assemblages do exist in the trade, where the components have been pulled together later from unrelated sources. They are not necessarily problematic, but they should be described as assemblages rather than as original sets.

Goldweight Pendants: When a Trade Weight Became Jewellery

Once colonial currency had displaced gold dust as the everyday medium of exchange, many cast brass goldweight forms were perforated and worn as personal adornment, retaining their visual language but no longer functioning as units of value. This transition — from currency object to ornament — is a documented and recognised strand of late Akan brass material culture, and pieces from this transitional period have a distinct collector audience alongside other forms of African body adornment such as African tribal bracelets and armlets and African trade bead necklaces.

What to look for in a goldweight pendant:

• Casting and motif language consistent with the goldweight tradition. Curved profiles, concentric motifs, fine linear engraving, balanced proportions characteristic of Ghanaian brass trade objects.
• A drilled or pierced suspension hole rather than a cast loop. The hole should show wear from cord or chain, not be sharp-edged or recently cut.
• Surface consistent with extended use as both a weight and later as a worn object — handling wear on prominent surfaces, possibly with rub-marks where a cord passed through the suspension hole.
• Mass that does not align cleanly with a goldweight unit. Pendants often retain enough of their original mass to be plausible weights, but once perforation has been added, the original calibration is no longer load-bearing for evaluation.

A pendant of this type is collected for its place in the post-1900 cultural transition, not for its functional accuracy as a weight. Its value comes from the combined evidence of original casting, original surface, and original or near-period reuse.

How Akan Gold Weights Were Made: The Lost-Wax Method

Akan weights were cast by cire perdue (lost-wax casting), the same basic process used across West Africa for bronze work from Ife and Benin to Bamum. The sequence:

1. Wax model. A model of the weight is sculpted in beeswax, usually over a small clay or charcoal core on larger pieces. Casting channels (sprue and vents) are attached in wax.
2. Investment mould. The wax is coated in fine clay slip, then progressively heavier layers of clay, until the whole assembly is encased. The mould is dried.
3. Wax burn-out. The mould is heated. The wax melts and runs out of the sprue, leaving a hollow cavity in the exact shape of the original model.
4. Pouring. Molten brass or bronze (a copper alloy with zinc, tin, or both, and variable small amounts of lead) is poured into the cavity.
5. Breaking the mould. Once cool, the mould is broken open. The casting cannot be reused: the mould is destroyed in the process.
6. Finishing. Sprues and vents are filed away, and the mass is adjusted by filing or, less commonly, adding brass to reach a target unit.

Every weight is therefore technically unique. Two weights of the same subject from the same workshop differ in small details of modelling, finishing and mass.

A small proportion of weights, particularly those depicting delicate natural forms (seed pods, beetles, crab claws, grains of maize, groundnuts), were made by fat-casting or direct casting: the actual organic object was coated in wax, burnt out in the mould, and replaced by brass. The result is an anatomically exact casting of the original object.

The Met Museum's overview of lost-wax casting is a useful general reference for the method, and the British Museum's Kingdom of Benin overview sets the related Benin bronze tradition in context.

The Garrard Typology: Dating Akan Weights

The standard reference for Akan weight typology and dating is Timothy F. Garrard's Akan Weights and the Gold Trade (1980). Garrard divided the tradition into four broad periods, which are still the working framework for serious cataloguing:

These are working categories, not precise dates. Individual weights are usually described as "17th–18th century", "18th–19th century", "19th century", or "19th–early 20th century" rather than with fixed years. A listing that claims a specific narrow date ("c. 1785") without provenance support should be treated with caution.

Niangoran-Bouah's three-volume L'Univers Akan des Poids à Peser l'Or (1984–1987) is the principal French-language study, and Tom Phillips's African Goldweights: Miniature Sculptures from Ghana 1400–1900 (2010) is the most accessible large-format photographic survey.

Mass and the Akan Weighing System

The Akan weighing system uses named denominations drawn partly from Mande / Dyula trade influence and partly from indigenous Akan terminology. Common named units include taku, damma, ba, agiratwe, periguin, benda, piampa and medwan, in multiples and fractions.

For buyers, the practical implication is simple: the mass of a period weight should fall on or close to a known unit value. A weight that lands at 8.6 g, 14.2 g, or 37.4 g is more plausible than one at 11.1 g, 19.7 g, or 33.4 g, because the former cluster around documented units. An arbitrary mass is a warning sign — either that the weight is a decorative recast (cast from an original mould but no longer trimmed to a working unit) or that it is a later piece never intended to measure anything.

Any serious listing should state the mass in grams. This single discipline separates serious dealers from generic ones in the Akan market.

Surface and Patina on Brass and Bronze

Brass and bronze do not develop patina in the same way as wood, but they do change over time. A period Akan weight should show:

• A settled, oxidised surface, often dark brown to near-black, with lighter brass or bronze showing on high points where the weight was handled or rested on a scale pan
• Slightly greasy or waxy feel from years of handling
• Wear rounded at the corners of geometric weights, and at the heads, hands and feet of figurative weights
• Flat, smooth under-surfaces where the weight sat in a scale pan or among other weights in a box
• Possible pitting from long burial or storage in damp conditions

A bright yellow, uniformly polished surface is almost always a warning sign. It indicates either very recent casting or aggressive modern polishing that has stripped the patina off an older piece. A clean, polished surface is difficult to un-do. An aged surface should never be brightened.

Watch also for pinkish "copper bloom" from overcleaning (exposing the copper-rich phase of the alloy), active green corrosion spots (bronze disease — these require specialist stabilisation and spread if ignored), and applied dark finishes (shoe polish, patination chemicals) that sit on the surface rather than integrate with it.

Tool Marks and Casting Signatures

Lost-wax casting leaves specific signatures that are worth learning:

• Imperfect registration. Fine lines of the wax model do not always fully replicate in the brass. Expect small irregularities, pitted areas, and the occasional missed detail.
• Bubble voids. Very small bubbles in the cavity produce tiny spherical voids in the finished casting.
• Variable wall thickness. Hollow figurative weights show uneven interior wall thickness because the wax layer over the core was not perfectly even.
• Sprue remnants and casting apertures. The casting channels are filed away, but usually leave a small flat or slightly rougher area, most often on the underside or at the base. These are positive authenticity features.
• File marks. Where mass was adjusted after casting, parallel file marks are visible. Positive authenticity signals, not flaws.
• Added material. Where mass needed to be increased, small pellets or wire fragments of brass may have been brazed on. Uncommon but authentic when present.

Machine-made reproductions show none of these features. They tend to be uniformly regular, with smooth sand-cast pebbling on the surface or the polished finish of investment casting. The absence of hand-finishing marks on a supposedly period weight is itself a signal.

Recasts (weights cast from moulds taken off period originals) are the harder case. A recast will show softened detail compared to the original, shrinkage of roughly 2–5% against the source piece (the casting contracts as the brass cools), an arbitrary rather than unit-aligned mass, and a fresher, less settled surface unless artificially aged. Comparing the piece with well-photographed published examples is often the fastest way to identify a recast lineage.

Provenance: Egon Guenther, Hans Himmelheber and the European Collection Routes

Akan gold weights enjoy an unusually deep published literature for a niche collectible, and that literature supports provenance work in a way that many African art categories cannot match. Reputable provenance references include:

• Old European collection stickers, labels or inventory numbers on the weight itself
• Prior ownership in named collections
• Auction records at Sotheby's, Christie's, Bonhams, Lempertz or Zemanek-Münster
• Publication in Garrard (1980), Niangoran-Bouah (1984–1987), Phillips (2010), or major museum catalogues

Two named European collections are particularly load-bearing for buyers in this market.

Egon Guenther

Egon Guenther was a significant 20th-century European collector and dealer in African art, with deep holdings in Akan brass material and West African ethnographic objects more broadly. Pieces from the Guenther collection appear in dealer and auction catalogues with the named-collection reference. The Guenther name carries demonstrable weight on the niche-collector market and in published comparables, and pieces from the collection are often visibly recorded in old inventory numbers on the underside or in the original storage trays. See our Egon Guenther Collection for current stock with this provenance.

Hans Himmelheber (1908–2003)

Hans Himmelheber was a German ethnologist whose decades of fieldwork in Côte d'Ivoire, Ghana, Liberia and the wider region, combined with substantial publication, shape much of the modern reference literature on West African art. Pieces with documented Himmelheber provenance — often passing later through other named collections, including Guenther's — carry an additional layer of authority. The chain "Himmelheber → Guenther → present collection" is one of the strongest paper-trail provenances available for Akan brass material.

Both names appear in the wider literature and on sale records, and a search through dealer and auction archives is usually enough to verify a published reference. Where named-collection provenance is claimed without supporting documentation, that claim should be treated as decorative rather than evidential.

The British Museum's Akan goldweight holdings and the Musée du Quai Branly's African collections provide independent reference corpora for typology, casting quality, surface condition and subject identification. A search through their published collection databases is an underused first step for any new buyer assessing a piece.

Common Reproductions and Attribution Traps

The Akan weight market has several recurring traps:

• Kumasi workshop recasts. Mid-20th century onward, workshops in Ghana produced brass casts for the tourist and decorative market. Many are skilled, but they are recasts or loose copies of period forms, not period weights.
• Polished "cleaned" weights. A genuinely old weight that has been aggressively polished loses both its patina and much of its value. A polished bright-yellow surface, even on a period casting, is a problem.
• Decorative "figurines" sold as weights. Some 20th-century brass castings were never intended as weights at all. They tend to be larger and heavier than period weights, with no consideration for mass correspondence.
• Overclaimed attribution to named carvers or workshops. Very few Akan weights can be tied to a specific workshop, let alone a named carver. Confident workshop attributions without published comparables should be treated with scepticism.
• Modern goldweight pendants. A drilled and worn period goldweight is one thing; a contemporary brass casting drilled and finished as a pendant is another. Look at the casting evidence and the surface, not just the suspension hole.

The single best protection is to compare against published examples in Phillips (2010), Garrard (1980), and the major museum databases.

Are Akan Gold Weights Valuable?

Prices in the Akan weight market cover a wide range. The bands below are indicative of the European market at the time of writing and should be reviewed against recent auction comparables rather than treated as fixed values.

Value is driven by a combination of subject, casting and surface quality, mass correspondence with a named unit, provenance, and typological references. A weight from the Guenther or Himmelheber lineages is significantly easier to sell and easier to value than an unrelated comparable.

A Practical Workflow for a Weight You Are Considering

1. Weigh it. Record the mass in grams. Does it fall near a known Akan unit value?
2. Examine the surface. Handle it in good light. Look for settled oxidation, handling wear on high points, and a consistent patina on all sides.
3. Check the casting. Look for lost-wax signatures — small voids, sprue remnants, casting apertures, file marks, variable wall thickness. Reject machine-smooth surfaces.
4. Identify the subject or type. Geometric (which shape family, which surface pattern), figurative (which subject), part of a documented group, a complete weighing set, or a goldweight pendant? Compare against Garrard, Phillips or Niangoran-Bouah plates.
5. Read the provenance. Ask for documentation. A documented Guenther or Himmelheber pedigree is a strong positive signal; an undocumented "old European collection" is not.
6. Compare against recent sold comparables in dealer and auction archives rather than against asking prices.
7. If in any doubt, ask a specialist or walk away.

A careful buyer applying this sequence will build a better collection, more cheaply, than one who trusts instinct alone. The market for Akan weights is small enough that bad habits propagate quickly; discipline pays back.
