What's the difference with Pics please. having a "Senior moment" understanding this........ 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 break. To be an Interior Die Break, the break must be larger than 4 square millimeters. Interior Die Breaks – Cuds on Coins Comments VERY welcome.
A Cud is a die break but it breaks on the rim. An Interior Die Break is no where near the rim. Unfortunately I don’t have photos on this phone.
