@paddyman98 Any idea what could have beveled the edges on this dime? Could the upsetting machine have done this?
I have seen a Rim Beveled on a nickel described as: "Strike was not strong enough to eliminate completely the original beveled junction between the planchet’s proto-rim and edge."
I'm not entirely sure what that means. I didn't know there was an original beveled junction on a coin, but that explanation sounds plausible. So it's basically a weak strike.
