The listing, 1952-S Lincoln Cent "CUD" Error has ended.
Cud Errors occur when there is a major die break in the coin making process. Just like anything that is struck over a million times a day, a coin die will eventually crack and a piece will fall away even though the dies are made from tool steel. As a crack progresses and reaches from side to side on the die, the portion defined by the crack will in most cases, fall away. When this occurs, as you can well guess, the next coins into the die will usually end up having a featureless blob on the face where the die broke. Granted, not the prettiest of errors, but cud errors are still a highly sought after item by coin collectors. I will not make any reference to the condition of this coin..You can judge for yourself from the photos.
