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.
Representative hosts
Exact local assets first
The Chinese slot remains visibly pending rather than borrowing a neighboring coin.
Reading paths
Follow the relationship, then return to the host
