I have a very odd Ohio Quarter (D) with a raised rim that is wider than both the face and obverse, causing each side of the coin to be recessed. The rim is smooth (no ridges) and is half-copper, half silver.
What would cause this? And (as most people ask, I imagine) is it worth anything?
I've heard that coins left in a dryer will end up looking like that one. Circulating clad coins do not contain any silver. The outer cladding is a nickel-copper alloy that has a silvery color. The only silver quarters now made are in special Proof sets.
What I'm not convinced on, though, is how a quarter in a dryer would cause the rim to expand evenly on both sides, uniformly all around, without wearing off the face or obverse. Also, the quarter appears to be a bit thicker than a regular one.
