| 正面描述 | A plain, roughly spherical clay token with an uneven, heavily textured surface showing the natural fired clay composite material. No intentional design device or inscription is present; the form itself — a sphere — served as the counting symbol, representing the numeral 100 or 3600 in the proto-Sumerian accounting system. |
