Lincoln Cent 1970's Cud

We have discussed die cracks, die breaks and cuds. I wanted to share with you photos of a Lincoln Cent with a pretty dramatic cud on the obverse:

Also note the characteristic that can help to verify that the error is authentic--if the cud is large, the detail nearest the cud on the other side of the coin will be weak or missing, due to the metal flow into the cud.

Pretty cool! Thanks for sharing.

We should really have a numisdoc of common errors and examples etc... This image would be a perfect example.
