Off center errors are planchets that was struck partially out from under the dies. These will be missing some of the design of the intended coin.
A Broadstrike is a similar error, but is NOT missing any design. It will appear larger than a regular struck coin, because it was struck out of its collar. It can look Off center and still be a Broadstrike error, if NONE of the design of the coin is missing
