Antique Brass Jewelry Coin Impression Die

This is an antique brass jewelry stamping die, approximately coin-sized, estimated to be from the mid-18th century (circa 1770s). The die features an octagonal perimeter harboring a complex, multi-tiered floral and mandalic design. At the center is a deep circular depression, surrounded by concentric rings of beaded patterns and a large outer ring of stylized lotus-like or flame-motif petals. The construction is solid cast brass, displaying a significant dark oxidation and heavy patina consistent with two and a half centuries of age and workshop use. Notable features include small concentric circle stamps at the hexagonal corners, likely used as registration marks for alignment. The surface exhibits several condition issues such as encrusted debris in the recessed areas, minor pitting, and softening of the finer detail lines due to repeated striking and historical wear. The craftsmanship represents high-quality traditional metalwork, intended for creating repousse or stamped gold and silver components for ceremonial or high-status jewelry. The sheer depth of the engraving suggests it was used with a mallet or press to transfer this intricate radial motif onto thin precious metal sheets.
