What is this on old copper edges?

I have some older coppers that have uniform notches on sections of the edge
- they do not correspond to the denticles - is this something that was caused after minting (screwpressing)
or part of the design/manufacture?
or did some enterprising individuals make some punch to uniformly take off a small percentage of each copper?

I brought this over here to see if anyone has better ideas than the US coin forum does
