Quote: But does aging of a zinc coin eventually turn gold?
Wouldn't matter here because there's no zinc involved in a Dime.
I think some foreign substance got onto it - acetone would probably pull it off. It could be a former science class project which has partly worn off in circulation.
Oh, ok. .. not zinc.... nickel.... Got it ;) and ok yes school experiment makes sense to me. Of all the things in the world science can experiment on... why coins? Dang it... they just don't know what they do to people like me when we come across a coin like this! Ugh -___-
Often times when I find a coin baking on the hot concrete or tar outside, it usually has a weird goldish color to it, or a brownish color to it. Just depends.
It seems to retain that color for a year or two, and sometimes just stays there. I've studied it a bit because I was interested.
I think this is the case, but I could be incorrect.
Nickel tones to many different shades, if the conditions are proper. I've some uncirculated Maine Statehood Quarters that were put in a jewelry case the year they were minted. They're now a nice shade of reddish-gold.
