Kevin SaucierI have to agree with Mark Anderson in that the plastic inserts, although not always attractive, keeps the card completely stable. I've inspected thousands of cards and have seen countless rail and gasket damage.
If you look closely at cards in PSA slabs, the damage will appear as an indentation (or worse) where the side rails end. Chances are, if you have a card that has been in a PSA slab for some time, you will definitely see this.
Lately, I have also been seeing more and more cards damaged by the SGC gaskets. The customized gaskets with sometimes sharp and/or fragmented sides, can actually saw away at the cards edges. It's not as prevalent as PSA but IMO will increase with time. You will probably need a loupe to see it.
