Russian Coin allegedly Ivan III 1400s [opgelost]

Greetings,

I bought this coin on the whim from a never before used seller. There is a certificate included from "Calhoun's Collectors Society" talking about it but I don't put to much faith in it. The seller claims this is called "wire money." It's very thin like an index card and oval shaped. I can't find anything in the catalogue. It is the size of a US number 2 pencil eraser. The weight is 0.40 grams exactly on my scale. Content is allegedly silver. Any help would be appreciated. Sorry about the photos as it's night here and I have to use artificial light. I don't know which side is obverse and reverse.

Yes, Russian wire money but not Ivan III. The writing appears to match a silver kopek of Mikhail Fedorovich ca. 1613-1645, Moscow mint.

Thank you! I think you're right on target. I can see the O and M in my photos under the horseman with spear though it seems this coin has been clipped off or something as the horseman and lettering are obviously missing parts. There are a lot of Michael I kopecks in the catalogue so I will have to study them. This helps though as the Ivan III was called Denga and none of them looked anything like my coin. Thanks!
