Sgc vs psa for card grading

thank you for the comment..., then this is a conundrum. It makes buying graded cards pointless, and also getting my cards graded is pointless! The amount of trimmed cards given a numerical grade must be overstated. Most seasoned collectors can spot a trimmed card, I'd imagine TPGs catch a good 80% of them. I would settle for showing my cards to a knowledgable collector, but unfortunately that is not really possible now*

Not overstated. There are a ton of threads on blowout with before and after pictures showing exactly how cards were cut down. Well worth a read if you're thinking about spending any money with grading companies.

Not so. Anymore. Except maybe the worst of them.

Also seems to be at odds with your earlier post that you yourself aren't sure and that at least part of the reason to consider grading was to double check yourself, unless I mistake your meaning.

Not sure how you figure the imagined number, but even if so, you might consider all the more reason that all your raw cards might be even more likely already altered, and possibly the worst of the bunch, if they've remained raw from already being rejected by a TPG, unless you got them straight from the attic of an estate sale or something.

I hear what you guys are saying, and I have seen the stories and pictures that have been posted on this site. Grading is definitely not perfect.

However, there are clearly some things that experienced people can spot, and there are plenty of articles written up about it. One of these below is from Beckett, so clearly they do have some tell-tale signs of alterations. if a TPG is magnifying a card and looking for threads on the edges, that is way more i am doing,... Now, if they hire bad graders, or have a lazy process that is another story. but either way, I imagine they will be better at than I am. If I sent in 25 cards and 5 came back "A", I'd stop buying cards altogether. If 1 or 2 came back "A", I would be pretty comfortable, and probably learn how to spot them.

Yes, but I think some critics in the forums would caution that this perspective doesn't validate the existence of "false negatives", to put it in the current medical parlance popularized during covid.

So for instance of the 25 hypothetical items you send in, only one comes back "A" but it doesn't mean they themselves didn't miss the other four that there actually were (if someone had a crystal ball with all the answers), which is the quantity that you estimated could swing your view of things...
