ID help with Japanese coin

Can anyone help me with this one? It came in a flip marked “HAKODATE” and “18th Century” 

weight: 13.2 grams

diameter: 35.5 mm

thickness: 2.35

thanks,

chris

I only know of one mon iron Hakodate coins and copper seed coins … no 100 mon coins.

My guess,  it's a fantasy piece.

Thanks, I can't find anything on google or in Krause, so you're probably right.

There are quite a few specimens on Japanese Yahoo sale sites but they are out of many different metals and always with the sentence no guarantee for authenticity 😉
