I came across this 2007 D Montana Quarter that has been in my coin jar for quite a few years. It is a different color on the reverse, and from looking around this web site I guess this is called "missing the cladding?" (plating)? It also appears to be a little light on cladding on the face side or its rusty! It also seems to have some damage on Georges cheek and jowel. (Damage from use or die damage)? Thanks for your input Dubya
