I first found this dime when I picked it up off the street, I thought it looked strange, But I just assumed it was dirty. Then I later found an almost identical dime of a different year, Now I'm curious...
I'm making a thread for both coins since they are so similar, One is a 2001 D, The other is a 1966. My guess is that they are either missing a clad layer, Or have some kind of discoloration on them. (Or they are just really dirty

)
