I bought this coin the other day, I'm not sure if it's real the reverse side has no design. Theres signs of a reverse design on it at all
That is a replica of a US half cent. Not sure why the reverse is blank, but it's not a real coin unfortunately
I've seen these before and owned a few. Supposed to be a 1809 key date large cent. Its a reproduction but they tend to sell for $25-$50.
