1863 IHP Need Variety Help (Cud And Die Cracks)

Cuds and die breaks are due to a die's age / wear at striking, and do not generally strike coins that are then considered a variety.

The variety would be, for example, a repunching of the date. Then, if there are Cuds or die breaks, they can be noted as die state A, B, C and so on to identify these due to age (since the Cuds and breaks would be consistent on every coin struck around that point in the die's life). Varieties can have higher value being struck from an earlier or later die state.

Non-variety coins with just a Cud or break can add some collector value, however. I don't think it would on such a low grade coin.

As far as this coin, the thing you see in the 8 appears to me to be some form of hit or damage, which can be seen on the other digits. Keep hunting!

Generally speaking, the more rotation there is, the higher the premium. I read on one of the cent sites that the mint tolerated margin of error is 8 degrees of rotation. I don't know that I'd even be able to detect your 2-3 degree variance looking at a coin and not knowing to look for rotated dies.
