Turns out this is a valuable key date from Hungary, NGCcoin website has a value of 3500 dollars for it. Yours looks to be about a VF+/EF condition.
I really want the coin to be authentic, but look at the detail under the 6 number. I uploaded 2 more pics to show it better. It looks like a little rounded lifted shape under it, I dont know how to explain it better. Is it possible for someone to modify a coin melting silver and add or modify a 6 later?
