Help Identifying a Japanese mon coin [resuelto]

Very new to coin collecting, inherited some coins from the 1800's to mid 1900's recently. I see that these can be pretty tricky to ID. Anybody have an idea?

Edit: Will take measurements and update soon. I can also take brighter pictures, these were just my cataloging pictures.

​Thanks for the link! I was looking at that and figured I probably wouldn't be able to spot the differences myself too easily. Was hoping someone that knows a little better might be able to tell me if it can be ID'd or not.

This is Shin-Kanei Tsuho. I think the type is Yottsuho-sen, minted in Kameido-mura / Edo (now Tokyo) at Hoei 5 - Shotoku 2 (1708-1712)
