The size and description of the feature are determinates for what it is called: Die Chip, Break, Gouge, Dent, Cud: Comparing Terminology Die Chip = up to 1 mm in length Die Crack = Ordinary die cracks often appear as thin raised lines that can follow a somewhat erratic path. Small Die Break = 1 mm to 3 mm in length Large Die Break = more than 3 mm in length Die Gouge = clear longitudinal striations within the body of the gouge (most feeder finger die gouges exhibit this). “Die Gouge” is also used with reference to features that do not have longitudinal striations. Die Dent = die is damaged by a known or unknown object which leaves a recess in the die face. The die dent therefore appears raised on the coin. Retained Interior Die Break: An island of metal surrounded by a die crack that sinks into the die face. Any void encompassing an area of 4² millimeters or more qualifies as an interior die break. Cud: A die break that involves the rim and at least a little bit of the adjacent field or design. (A Rim Cud involves only the rim).

Good eye. Die chips like these are though, very common on modern dimes. Still a keeper if you like it. I save all mine.
The learning curve in some areas can be the difference between climbing a small hill, and climbing the Matterhorn. LOL
