Hey John1- I wondered the same thing. I do a little metal detecting and these clad coins come out of the ground pretty nasty if they have been under awhile. It sure could have been in the ground, but someone would have to dipped it in some acid to get the corrosion off of it.
Hey coop- thanks for that post-it on acid treatment. I didn't know about the edge loss like that on a coin. I appreciate it, learned something new today! I double checked that New York quarter and the edging seems to be normal, so I bet it got a light bath.
Guys, thank you for your welcome and the tips....man keep them coming! Thanks again.
