PART VI. Striking Errors:

Broadstrikes

Definition:A coin that is struck outside the collar.  The collar is the retaining ring that establishes the final diameter of the newly-struck coin.  A broadstrike will expand beyond the diameter of a normal coin, sometimes drastically so.

A perfectly centered coin that is struck out-of-collar is simply called a “broadstrike”.  An imperfectly centered coin that is struck out-of-collar is called an “uncentered broadstrike”.

In order to qualify as a broadstrike, the full design must be present on both faces.  If the design is cut off on either face, it is called an “off-center strike”.

The images below show a 1916-D Lincoln cent that has assumed the form of an uncentered broadstrike.

The images below show a broadstruck 1997-(?) Washington dollar coin.  Due to its enlarged diameter, this dollar coin did not receive the edge inscriptions.
