Japan Coin Catalogue

All the coins of Japan classified by type, collectors call it: classification by #KM (acronym of the publication in charge of giving them number). In this catalogue you can find currently coins in circulation ¥ - Yen and old coins of Japan distributed in their historical categories.

The value of the coins has been calculated using our precise algorithm by obtaining the market prices included by collectors, taking into account their characteristics: material, weight, diameter, edge, year of minting, mint of manufacture and mintage. The most valuable Japan coins are those which have had the least production and the best preservation.
