For a PSA card the best way to research it IMO, in addition of course to seeing who is selling it and to scrutinize the scan closely and the card when you get it, is to search the cert and surrounding certs on the PSA website. They provide key information such as who first sold the card, if they are able to pick that up from ebay or certain auctions. And sometimes you just get a bad gut feel from what else is in the sub, like if it's all 10s on modern stuff.

I don't think anyone has a complete database of outed certs. I had one for a while but didn't keep up with it after early 2020. In any event the outed certs are, IMO, a small fraction of the altered cards out there. Probably very small.

If you care, do your diligence.

Completely agree. Even though BODA has exposed thousands of altered cards in PSA numbered slabs, there are easily a dozen times this number in circulation.
