I was looking at the three silver 3-cent coins in my type set. Two show the results of an obvious die clash on the reverse. But not on the obverse. I assume the obverse dies were beyond help and therefore replaced. A die clash is what? An error? A variety? Something else? ~~~~~~~~~~ The third silver 3-cent has about a 180 degree die rotation. A die rotation is what? An error? A variety? Something else? ~~~~~~~~~~ I know these questions have been addressed before, but this time when I get the definitive answer I'll save it so I don't have to re-invent the wheel each time.
Both are errors made at the time of minting. Die clashes are pretty common, unless clashed with some other coin, then they can be worth a premium. And die rotations are also common and can be worth a premium if the rotation is major, usually if 90 degrees or more.
Thanks. I gather then that both are classified as errors. Just to show you what I'm talking about, here's the coins: On the Variety 1, look at the "ghost" of the star on the reverse. On the Variety 2, look at the shield lines in the gaps of the "III". And finally, on the Variety 3 you'll have to take my word for it that the reverse is about a 180 degree rotation.
