I have some sports cards that are slabbed by Beckett , I did not have it done , they came that way , every one does not show up in their certification via their online search
Has anyone experienced this, here is a example of one that did not show up
Where are you searching for the cert ? Bear in mind that this item was slabbed by "Beckett," the card grading unit. Not the same as "Beckett Authentication Services" (BAS) the autograph authentication division. I suspect their cert number systems are different.
