Lincoln Cent Retained CUD
CUD mint errors are found on the edge of the coin only and start with a break in the die and move inward from the rim. The more dramatic the CUD and the higher the grade of the coin determines their value.

Coins can obtain one CUD or multiple CUDS or the beginning of a CUD called a retained CUD.
