Interior Die Break:

Connected to a Die Crack or Split

Definition: When a thick flake spalls off the interior of the die face it leaves a void we call an interior die break.  It appears on the coin as a featureless lump.  Unlike a cud, an interior die break has no direct connection to the design rim.  Interior die breaks are often connected to die cracks and sometimes straddle a split in the die face (split die).  When it is not connected to a die crack, it is called a freestanding interior die breaks.

This 2007-D dime was struck by a shattered obverse die.  Many forms of brittle fracture are evident, including a 50% retained cud and many bi-level die cracks.  A large interior die break has replaced Roosevelt’s mouth and cheek.
