New to collecting, sticks to magnet, steel? How unusual is this coin, could not find any info. It's a 2001 north Carolina. Value?
It suffered Environmental damage after it left the mint. Probably a metal detecting find since it looks like there is still some soil residue on it. There are a lot of posts on Coin Talk asking about discolored nickels, dimes and quarters, just like yours. Sorry, but it's only worth a quarter.
I don't see how oxidation of a clad would magnetize it. The only pure metallic elements that are "magnetic", in the sense that they will stick to a magnet, are iron, cobalt and nickel. Almost-pure alloys of any of these elements should be magnetic, too. Steel has iron in it. But the clad quarters are mostly copper, the core being copper and the outer layers being 75% copper and 25% nickel. Not enough nickel to be magnetic. Please show a photo of this coin sticking to a magnet.
