As I was sorting a roll I came across a 1955 cent. I was examining it closely to see if it was a double die. No such luck. I flipped the cent over & the other side was a 1948 cent. Some ground the 2 pennies down & fit them together to give a 2 headed cent. Very neat job. Same thickness as a normal cent & you could barely seem the seam.

That sounds pretty awesome! You should post pics of that if you can.
