Exonumia, Bulgaria [résolu]

A friend of mine found this on the road. 

I see a pattern, on numista at the exonumia of this. 
what could this one be?

They found this N#111460 lying on the road?

That's mine … it must have dropped out of my pocket when I went shopping last week. Please send it back to join the other 12 ex. I have at home … thanks.

Edit: some copy. Check lettering on CoA !

Thanks! If it’s a copy, understandable haha.

Didn’t think the jackpot would lay on the street!
