From the estate of my late mother, who owned an import shop in the late 1970s. She traveled all over the world buying. This coin is from her shop days. 

One antique 1636 Japanese 1 Mon coin. Coin measures 23.75mm in diameter and is 1.3mm in thickness. 

Note: an AI scanning app called CoinSnap was used to identify this coin to the best of my ability. I cannot guarantee the accuracy of the scanning app.

Coin I

Note: Buyer can choose between Ground Shipping/First Class ($4.25) or Standard Envelope for Coins ($1.50). I have found that Standard Envelope is often delayed, and rarely tracks, so please have patience if this is your choice. While I have many super powers, I cannot control the US Post!
