Context
Historical and monetary setting
The Bank of Japan Currency Museum identifies Mexican silver dollars as the principal foreign coins received during the opening-period exchange. Their acceptance depended on rules, weight, fineness, and merchant practice.
Identification
How to classify the evidence
Identify the foreign host coin under its issuing jurisdiction, then record Japanese circulation, testing, valuation, and any post-strike marks separately.
