Edge flaws impact the grade as opposed to merely being qualifiers like centering.
Bottom line, if you find yourself squinting or using various scoping devices to analyze an edge,
you are probably dealing with a card that has nearmint or better edges. Scoping
devices are needed to separate nearmint from mint which I am not going to spend time
Rubberband: Just as it sounds, the edges are dimpled probably from being squeezed by a rubberband for years. Can't be rated higher than Ex.
Trimmed: Edge isn't evenly cut all the way. Some unscrupulous folks will do this to square off an imperfect corner. It is important to note that often cards come from the pack with uneven edges due to no so perfect factory cutting. I refer to obvious trimming which can often be seen with a jagged edge or a random "point" along the edge. This post factory trimming drops a card to poor as far as I am concerned.
Slippage Image:Sticker image insider border has slid. Can come from the factory this way but can also be the result of someone resticking the sticker with no so successful results. Tough to rate a card higher than Ex with this flaw.
Slippage Edge:Whole entire sticker, border and all has slid. Can come from the factory this way but can also be the result of someone resticking the sticker with no so successful results. Tough to rate a card higher than Ex with this flaw.
Dirt:Most of the time, what appears to be a hideous flaw here can be wiped away rather harmlessly with a stocking or your finger pressed inside a clean rag(or long sleeve shirt as I have been know to use). Won't degrade card if wiped away successfully.
In general, any of the edgewear above is pretty significant and drops the card to Ex. Any lighter wear and tear edgewear can allow a card to be Ex+ or even Nrmt if you find yourself using a scoping device to spy it.
