I found the study.
Probably will never find that if my coins were genuine or fake. And thats make sence...
Btw do u have a pictures of ur flase coin? Did it had the same edge subsription like the my ex coin?
Тhe story about the coin is ironical...
I am from Bulgariam until 1989y Bulgaria was in the USSR area of influence, very close relationс, closed geopolitical system,
almost closed visible trade and more with that meaning.
I acquired the coin maybe in 1990y, was just a kid, about 12y old, i didnt know nothing about the coins, or professional collecting, just then were very popular between the kids, to change everything, coins, cartoons, magazines.
So i acquired the coin from another kid vs coins, and later changed it for a lot of magazines.
