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.

Host coin

Keeps its issuing country, authority, type, date, mint, and issue ID.

Circulation

Adds a dated jurisdiction relationship; it never creates a domestic issue.

Post-strike event

A chop, official countermark, cut, or graffiti stays attached to the host.

Production

Mint facility and client authority remain separate from the issuer and canonical country.

Canonical Mexico hosts

Recognizable silver did not mean universal acceptance

Weight, type familiarity, merchant testing, customs practice, and local preference could all affect acceptance. Every relationship below remains local and time-bounded.
