Japan 100 Mon Tempo Tshuho (Oval Coin, Square Hole) 1835 to 1870

What you've probably got, Lou, is a bronze 100 mon coin from Japan. There are a few other patterns of Asian logograms, but the one shown in our picture is the most common. It is hard to miss the unusual shape.

Coins with the pattern shown catalog like this:

worn: $5 US dollars approximate catalog value
average circulated: $15
well preserved: $25

If your coin has a different pattern, it is probably worth more. Take it to a coin dealer or knowledgeable collector, or send us a picture by stating an e-mail exchange with CoinQuest (see Contact Us link).
