it looks identical to other Yen from this era, and the flip side is nothing interesting, what I’m wondering about is this “415”, all other yen that I can find pictures of have “416”.
this number is the weight of the coin which was normally 416 grains.
but somehow I have one that weighs 415 grains, a version of the coin that is not listed as existing on Numista.
The only other person I can find talking about a coin like this online is someone from china on Baidu, but I had no luck there in finding out if it’s rare or not.
