Rim Splits, Fins And Cuds

Cuds do add value to a coin, especially if it's a major die break.

yep, I agree with Marve here.
do you have any coins like what you described above?

Dearborn, photos of rim splits as asked about are they of any value to a seller or a collecter.

That's the result of a slightly misaligned die striking the coin.

Two things to remember, first the planchet had a "proto rim" created prior to striking by the upset mill and second the actual rim is cut into the die.

This means that when struck properly the proto rim is obliterated by the rim feature on the die and when the die doesn't line up properly both rims will remain, although the proto rim will only remain in the area of non-alignment.

Some might refer to this as a Rim Fin, but I've always understood a fin to be a section of the rim that extrudes upwards from the planchet due to excessive striking pressure, much like the fin of a fish rising above the surface of the water. If the outer rim area is level with or below the inner rim feature I don't think of it as a fin.

Done.
