Identity before movement
One coin, several relationships
The network explains movement without turning a Mexican coin into a Chinese issue or a Japan-minted foreign coin into a Japanese issue.
Keeps its issuing country, authority, type, date, mint, and issue ID.
Adds a dated jurisdiction relationship; it never creates a domestic issue.
A chop, official countermark, cut, or graffiti stays attached to the host.
Mint facility and client authority remain separate from the issuer and canonical country.
Government act, not private chop
Two documented official post-strike cases
| Mark | Host | Authority | Date | Legal effect |
|---|---|---|---|---|
| 改三分定 | mx-denom-eight-reales | Tokugawa shogunate | 1859-12 to 1860-05 | Time-bounded official circulation value in Japan; host remained a foreign silver dollar |
| 銀 | jp-series-meiji-silver-yen | Japanese monetary authorities | 1897 | Post-strike administrative status; host remained a Japanese silver yen |
GIN / 銀
Unmarked host shown for identity only
The local image is an exact 1889 silver-yen host but does not show the Gin punch. It is not presented as an exact countermarked specimen.
