hier die Antwort eines Spezialisten aus USA zu deiner Münze:
parallel hierzu habe ich dir auch noch eine PN geschrieben.In any case - this coin was minted at the time of Ioan Sratzimir (1356-1396) or shotrly thereafter. It is presumably an imitative issue due to its crude design. Although some authors would say that it is an official Sratzimir issue (see for example Radushev, Catalog of Bulgarian Medieval Coins where the obverse looks like Radushev 1.14.20-22 but the reverse looks like Radushev 1.14.14-15), I think it is an imitation. The thing is that there are many coins from his reign that have not been studied and there are literally hundreds of variations. I have about 50-60 variations that have not been published. Thanks again :)
Best Regards,
Blago
