The most often seen errors within the Mercury Dime series are laminated planchets, broadstrikes and off-centered coins. These are not especially difficult to find, but all other error types are quite scarce. Exotic pieces such as double-struck and wrong planchet errors are very rare.
The following collection of errors was assembled from a variety of sources, as noted. The photographs are arranged in chronological order. The author would like to take this opportunity to extend a special thanks to those who shared with him these instructive and amusing examples of the minting process gone awry.
