Picked these 2 up in the junk silver pile for 7 bucks a piece. The 1920 looks to have been dipped or buffed,,possibly both,,,but it filled a hole. The other looks to be a 1918D,,,maybe even a 1919D. Maybe one day someone will come up with a way to reveal the worn dates off of silver coins. I couldn't pass them up for 14 bucks though.
