Date off flan, contemporary fakes exist

Judging by the quality of dies, it looks genuine to me, the off-center strikes were common on that type and there was barely any silver in them (they were mostly copper).

Hm... I must disagree.

First, this is the page your type belongs to: https://en.numista.com/catalogue/pieces41643.html.

While the original coins have a low silver content, the Suceava counterfeits have an even lower silver content. From the pictures provided, my first thought was that the tone is closer to one of the counterfeits, and that the first C on the obverse is crude enough to... well, not be from a real piece. Also, the off-strikes are common on both the real pieces and the counterfeit ones, so that is not something that would really help.

That date would help the most with this. Looking at the date, it ends in a 0. That means this coin should either be dated "40" (and be real), "50" (and be real), or "60" (and be counterfeit). The bottom of the first digit of the date is curved, so not a 4. While the top of the first digit is not visible, the bottom left end is curved up. If that digit was a 5, the end would come to a point and not curve up. The counterfeit "60" coins, on the other hand, do have the bottom of the 6 being curved.

My conclusion: this is a Suceava counterfeit dated "60".

Thank you for all of your insights and support. I really appreciate the help!
@Sulfur: An especial thank you for providing an in-depth analysis, I enjoyed reading the passage quite a lot! The deduction was clear and coherent, and now it all makes sense to me. Once again, thanks.
