Tracking a PSA Certified Item

[Exhibitman]

So answering the OP question, you can look up the card by cert # on the PSA web site to confirm the cert # matches the slab cert # for the item [e.g., a Mantle signed card on the site should be a Mantle signed card in the slab]. It does not tell you when it was slabbed, who sent it in, etc., nor does it mean that the item is necessarily the item that was sent in. There was a scandal a few years ago over a dealer cracking cases and putting in lower grade cards then sealing and selling them. I suppose the same could be done to a signed item in a slab if a crook was so inclined. If you question the item itself, best to pass on it but if all you are looking to do is confirm that the item listed for the cert # matches the item you are looking to buy, then the site will give you that. As for the ink, as far as I know, it is just a streak and it fluoresces under a special wave length of black light. Pretty much useless for your purposes.
