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.
Facility is not issuer
Production edges preserve client and country identity
Japan Mint production for East Hebei or Mengjiang remains Chinese historical coinage. Dutch East Indies trial evidence is not promoted into a circulated issue.
