Curious if anyone knows whether the cert ID on PSA slabs can be used to approximate the date that the card was graded? If so, is there any documentation on which ranges of Cert IDs correspond to certain date ranges?

Hey everyone,

Lately I’ve been really interested in cards with in-person autographs and have been thinking through different player–card combinations that would make great pieces. Most recently, I’ve been focused on Messi, and I’m curious what others think.

If you could pick just one Messi card to have signed (say, in-person), which would it be, and why?

Would love to hear your thoughts!
