Half with a Strange Rim?

[Furismo]

Awhile back I was going through a box of halves and found a half with a horizontal line instead of a normal rim. I might post a picture tomorrow.

Strange error perhaps?

ive gotten them from time to time, in fact got one just yesterday, i throw them back tho cuz i think its cuz they get caught in the coin counter and it "sands"/grinds away some of the copper on the edge, but post a pick just to be sure because i could be wrong.....i hope i was wrong tho and u found something valuable! keep it up and hh!
