I dug this one up, seemed to be the most recent I could find. Date ranges included on some but not all.

Flip designs don’t help if the seller re-holders the card.
Plenty of sellers capitalize on that, as a lot of buyers pay for plastic slabs and meaningless assigned numbers

It does if you decide to take the time to catalog cert numbers by flip, for those in the original holders.

John, please explain. If I am buying a red cobb say and its in a shiny new PSA slab, how can determine when it was actually graded? I would have had to have tracked that cert number from the PSA database from the beginning, no?

I can’t help with the reholder question and from what it seems is the serial numbers are not reliable for dating.

This is a link to a google doc to help date by design, so it is of some help but the reholder issue does water it down.

This is exactly the question at hand.

If 06000001 is the card you're talking about, and card 06000123 has the flip style normally seen during the 2006 timeframe (just an example, not accurate), then 06000001 was very likely first graded during the same timeframe.

It is possible that the card also received a grade review bump somewhere down the line, but if it has the original cert number you can see the original era it was graded.
