1 Cash - Cảnh Hưng Tống Bảo, Regular script, with crescent and dot

Cảnh Hưng was the longest-reigning monarch of the Later Lê dynasty, ruling nominally for nearly half a century while the Trịnh lords exercised actual power in the north. The sheer duration of his reign — 1740 to 1786 — meant cash coins issued under his era name were produced in enormous quantities across multiple casting runs, which is precisely why variety collecting within this series has become its own subspecialty. The crescent and dot marks on this piece served as foundry or batch identifiers, distinguishing one casting from another rather than indicating mint location in any formal administrative sense.
