What I really want to know is what happened to this Roosevelt 2003D dime? The obverse and reverse are in reasonably good condition but the metal just looks off, as if it were aluminum exposed to the environment for rather a very long time. Then the edge; it's as if the copper shrunk or the NiCu outside expanded. I first thought someone was having fun with tools and did something to wear down the inner copper; however, the copper is reeded (i.e., not smooth). I hope y'all can see that on one of the wretched photos. Has anyone seen something like this before? Anyone have a clue how (and why) this is done?
