Minted in Japan over 300 years ago, "New" Kanei Tsuho 1 Mon coins were made from 1668 to 1868 in the Edo Period by the Tokugawa Shogunate.

These 1 mon coins were the standard coinage until 1891. They have been around since the height of the samurai era and could have very well been used by notable samurai including Miyamoto Musashi (1584-1645) and Sakamoto Ryoma (1836-87), and ninja clans such as the Iga and Koga. 

In its day a Mon coin would be used for small transactions, like buying a simple lunch (4-5 mon). Large amounts of coins could be strung together thought the square hole and tied to a belt for easy transport. A single mon might buy you a small fish or a pastry.

The obverse or front face inscription translates to "Currency of Kanei". This kanji mark was used until the late 1860's despite the Kanei Era actually ending in 1643.

The reverse or back of these "Old" (1636-1659) coins are generally blank, but some may have "stars" or dot mark and rim symbols depending on the maker.

Mon coins were not marked with exact minting dates and manufacture was spread among many smiths and artisans throughout the country. "New" kanei tsuho coins minted after 1668 may have mint marks on the top center of the coin back.

I have tried to mark any large holes or crack in coins with a red arrow on the reverse image. Please keep in mind these are actual antique coins that are over 300 years old, they are in used, worn conditions which is a large part of their charm!
