Expected Dime weight missing one clad layer = 1.863 g +/- 0.091 g; missing two clad layers = 1.453 g +/- .161 g The coin weighs 1.88g - within Tolerance for missing one clad layer. Expected thickness of clad layer: Dime clad layer (75% +/- 2.5% Cu and 25% +/- 2.5% Ni) = 180.34 µm (+/-25.4 µm) Thicknesses measured for this coin: @ motto = 1.03mm @ struck through = 1.05mm @ date = 1.08mm @ R in LIBERTY = 1.03mm The most interesting feature is what a think is a clash on the copper core. I have never given any thought to how deep a clash might go on a clad coin, and have never seen one on the copper core. This one seems to be slightly misaligned. I think it is not unusual for a clash to be slightly misaligned or even slightly rotated. The coin also has what appears to be an Internal Die Break on the top of the head. Comments welcome.
