I received a quarter today in the store and it caught my attention when I noticed the side of it. Lined up with the rest of my changed I say that the side was really bright like a new penny would be. The ridges are slightly worn. Thinking it might be a newer quarter I turn it sideways to check the date. I notice it is really worn obverse and reverse sides. my question is it possible to be in a different metal ? Is that year one to look for for something like this. Is this something to maybe weigh ? The sides where the copper shows really does look real bright like a new penny ? Thoughts?
