| 表面の説明 | Irregular square brass weight of the abrammuo geometric type, produced by the lost-wax (cire perdue) casting technique. The field is divided by raised linear ridges forming a cruciform grid pattern, with horizontal parallel striations filling each quadrant, evoking a stylised architectural or textile motif. At the centre, a prominent raised spiral or volute device — likely an Adinkra-derived symbol — projects from the junction of the vertical and horizontal dividing lines. The surfaces display the characteristic roughness and slight irregularity inherent to hand-finished sand or clay mould casting, with a dark bronze-brown patina consistent with age and use. |

| 裏面の説明 | Plain, undecorated reverse surface exhibiting a distinctly convex, cushion-like profile with gently bowed sides, characteristic of the geometric abrammuo class of Ashanti gold weights. The surface is entirely featureless and bears a heavily granular, pitted texture resulting from the casting process and subsequent oxidation. A deep, uneven dark brown to black patina covers the entire surface, indicative of long circulation use as a trade weight in the Akan gold-dust economy. |

Ashanti gold weights were not currency in any conventional sense — they were the measuring instruments of a sophisticated gold-dust economy. Each weight corresponded to a unit in the local system, ultimately tied to the weight of specific seeds, most commonly the hyedue (Abrus precatorius), before the system was later rationalized against Islamic and European trading standards absorbed through trans-Saharan and coastal commerce.
At 72.8g, this example sits at the heavy end of the functional range, consistent with weights used by senior traders or state officials handling large transactions. The Asantehene's treasury maintained its own calibrated sets, and discrepancies between a merchant's weights and the royal standard were treated as fraud.
