Perhaps worth noting is that rough cuts, in general (at least the heavily frayed one's we're referring to above since most vintage cuts are technically "rough" somewhat), should only appear on the left and right edges. The only exception to this rule that I'm aware of are the OPC hockey cards where all 4 edges have rough cuts. I'm sure there are other sets I can't think of off the top of my head, but generally speaking, rough cut edges are only on the sides. The reason is because those were caused by the rotary sheets cutters that they ran the full sheets through. After they ran the sheets through those, they would end up with long strips which they would stack together and then used guillotine-style ream cutters to slice the stacks and create the top/bottom cuts. This is also why there is much more variation in card sizes from top to bottom than there is from left to right. Cards came short and tall with extraordinary variance from factory (upwards of 1/4" at the extremes), but they had very little variance from left to right (usually 1/64" or less for Topps). The majority of trimmed cards are trimmed top to bottom for this reason. Although there is certainly no shortage of trimmed left/right cards in slabs.
