What Maniac and Irv said.
With edges etc, it's more about them being "as manufactured" OPC just didn't do smooth cuts. That's as much a product of the cardstock used as it is the slitter knives.
To not accept that rough factory edge would be odd. Sort of like downgrading a 51 Topps for having round corners and perforations.
Now if the typical factory edge was perfect, then a rough one could be seen as a manufacturing flaw and graded lower.
