15 Monme 'Fukuchiyama Gin'

Fukuchiyama Domain, a small han in Tanba Province, was among the many feudal domains that issued unofficial silver currency during the Edo period to manage local exchange when centrally minted coinage was scarce or inconvenient for regional commerce. The monme-denominated system these domains used was tied to weight-based silver accounting rather than a fixed coin standard, making pieces like this one functionally closer to bullion tokens than conventional coinage.

Han-issued gin of this type were technically prohibited under Tokugawa monetary policy, which reserved currency issuance for the central government. Most domain silver was quietly tolerated until the Meiji reforms swept away both the han system and their currencies simultaneously in the 1870s.
