Part V: Planchet Errors:
Pre-strike Damage:
Definition: Pre-strike damage is any damage that occurs after blanking but before the strike. Its appearance is quite diverse. Planchets can be scraped, gouged, folded, torn, crimped, cut, and crushed.
In the case of copper-plated zinc cents, damage can occur before plating or after plating.
In the case of Presidential dollars and those Sacagawea dollars with edge lettering, damage can occur after the strike but before lettering is applied. This can be termed “post-strike/pre-lettering damage”.
Illustrations:
This off-center 1964-D nickel was struck on a planchet that was mechanically severed before the strike.
