Part VI. Striking Errors:

Brockages:

Brockage From Large Dropped Filling

Definition: A brockage generated by a large dropped filling. Such errors occur when a large flake of die fill separates from one die and falls onto, or attaches itself to, the opposite die. Such brockages can also occur when a large flake of die fill flips over onto a planchet. Normally-oriented incuse impressions of large, multi-element dropped fillings are rare; mirror-image incuse impressions (brockages) of multi-element dropped fillings are even rarer.

This 1993 cent features an in-collar, first-strike brockage of the obverse design on the reverse face. This error began when a large flake of die fill fell from the hammer (obverse) die onto the anvil (reverse) die when a planchet failed to be fed into the striking chamber. The flake could also have been directly transferred to the anvil die during a clash. The next planchet that was fed into the striking chamber (this coin) landed on top of the dropped filling and the two were struck together, generating the brockage.
