FWIW I've seen this attribute called "spike head". Would this be considered in that group, or just a die break?
All "spike heads" are die breaks. The term is just a clever marketing term to describe a die break from his head to the rim. You can see a catalog of them here. Apparently, there is a group dedicated to collecting these. Of note, your example is not listed. Contact them and you might get it listed! http://cuds-on-coins.com/lincoln-cent-spike-heads-1980-1989/
Yours looks more like a linear plating blister than a die crack. Based on the pictures, I'm like 99% sure that's what it is.
