1 Cash - Cảnh Hưng Vĩnh Bảo

Cảnh Hưng was the reign title of Lê Hiển Tông, who ruled for 47 years — the longest reign of any Lê dynasty emperor — though real power rested entirely with the Trịnh lords throughout. The Vĩnh Bảo series was cast over several decades of that reign, during which the northern Vietnamese economy ran on a chaotic mix of officially cast cash and a flood of privately cast counterfeits that the Trịnh administration repeatedly and unsuccessfully tried to suppress.

Barker's subdivision at 76.1 distinguishes this piece by specific calligraphic and metric characteristics that accumulated across successive casting runs.
