Definition:
A retained struck-through error occurs when the foreign object is embedded and retained in the struck coin.  Other terms are “struck-in error”, and “embedded struck-through error”.
Steel “staples” are sometimes found embedded in coins.  They are not really staples at all. Instead they are believed to be detached bristles from wire brushes used to clean encrusted gunk from the surface of dies.
This 1966(P) Lincoln cent was struck with a “staple” resting on top of the
planchet
.  The “staple” has been retained, making the specimen much more desirable than a coin with merely the impression of a “staple”.
