A 40X magnifier and some knowledge will usually cover them easily. The 40X magnifer is <$10. My first one cost 7 at a antique shop that sells supplies, my next few were about 2 each in a lot on ebay. (5 for 10?) 10 for 20? I don't remember. )
The knowledge is a bit harder to come by, but it's out there.

I'm not sure about a spooned out crease. To my knowledge I don't own any cards with that. It should be detectable.

I believe that in theory it should be possible to trim a card so that almost can't be detected. Almost. It would take some fairly involved equipment, but nothing that isn't readily available.

Some modern cards will be really hard. Some of the Topps Gypsy Queen base cards are a combination of die cut and knife cut. Different edges have different qualities right out of the pack.

I would think, and maybe I'm wrong, that unless you trim all four edges, at some level of magnification the trimmed edges will look different from the others in some way, despite efforts to make them look the same post-trimming.

Even trimming all four, getting a new edge looking like an old edge is hard. Maybe not impossible, but very hard.

The science used in other areas of collecting and history is so sophisticated that, for example, it can tell you when an artifact was buried in the ground by measuring the atomic energy released since it was hidden from sunlight.

Yes, I think science could be used to conclusively identify all sorts of alterations, including trimming, in trading cards.

Whenever I'm asked to examine an item, I ask "Where'd you get it?" The answer may just be that they picked it up in a garage sale or found it in an attic, but I expect an answer. If it was bought in an auction, I always check out the auction listing.
