1 Cash - Cảnh Hưng Cự Bảo, with Nhất

Cảnh Hưng was the longest-reigning monarch of the Lê dynasty's restored period, holding the throne nominally from 1740 to 1786, though real power shifted progressively to the Trịnh lords who governed from Thăng Long as regents. The cash coinage struck under his reign name is consequently vast in variety — Barker catalogues dozens of distinct types under the Cảnh Hưng series, distinguished by reverse inscription variants like the Nhất marker here, which likely denotes a specific furnace, batch authorization, or mint supervision group rather than a face-value increment.

Toda 114 places this among the more closely documented varieties. The Nhất character was one of several numerical and auspicious characters applied to reverse fields to differentiate casting runs across northern Vietnamese foundries.
