[QUOTE="-jeffB, post: 8088471, member: 27832"]Okay, so I'm trying to learn from my mistakes here. First, that much weight discrepancy implies [I]something[/I] was missing when struck -- by the time you've got enough corrosion to drop more than 20% of the weight of a coin, it's going to be [I]super[/I]-obvious, and probably affect more than the one face. But a single clad layer for a dime doesn't weigh that much, does it? (I know, I could look it up.) If the clad layer were [I]missing[/I], I'd expect a color typical of copper. I don't see that, and I compared the color of the 2x2 to make sure it wasn't just the camera "fixing" white balance. And I'm pretty sure I see little splotches of copper color around the rim in that first shot. I could see those being rolled around to the face during upset, if the punching process dragged the copper core far enough toward what eventually became the coin's obverse. But if the obverse clad layer were [I]missing[/I], [B]the whole face[/B] would be that color, disregarding splotches or other toning patterns that formed afterward. Where am I running off the rails?[/QUOTE]
