Is it possible to tell when an PCGS coin was graded?

PRECIOUSMENTAL

I have several PCGS coins in their OGH.
I can obviously enter the cert. #'s through their verification, numbers and coin match.
However, is their a data base linking cert. # to the date when it was slabbed?
Thank You.

Short answer is NO. Only PCGS knows and they aren't telling.

You can only approximate by the holder/label.

This might be a good starting point.


I don't think you will be able to get an exact date, but if you can match your slab up to the examples in the link I provided, that will at least give you a rather specific time frame....


I'm interested to see if anyone else can provide a way of finding a more accurate way.

Seems like the site can use a minor update. The last PCGS slab there, 23.1, mentions being used in 2006.

Keep in mind that the generation naming convention from the Sample Slabs site, linked above, does not match the generally used convention for naming PCGS generations for non-sample slabs as used by Conder101. Also, Cameron Keifer, who ran the Sample Slabs site, passed away nearly five years ago so it might not be maintained at all.

I've observed or interpreted that I've observed that the cert #s aren't even sequential to when they're graded. I think I observed when I sent coins off last March to get graded is that the cert #s were lower than coins I was seeing on Ebay.

PCGS has their reasons for wanting the grading dates obscure.

This is probably a better link for slab generations.

My understanding is that PCGS knows when each cert # was slabbed, but that is proprietary information.

It's their secret to tell and they won't.

Thank You for the information.
Why is it such 'privy' information?
Changes in tightening-loosening grading standards, perhaps for a particular series?
Do the 'Big 3' have this policy?
(IIRC I have a few old ANACS holders, where you have to cross reference the cert #, (alpha-numeric code) and you get an approximate dateline)
Again, Thanks, Have a Great Week!

I expect that they feel that you don't really have a need to know. All it does is propagate myths, rumors and innuendo like some of the stuff in this thread which more likely than not aren't true.

>lkeigwin<, Thanks for posting the link.
I only have one coin handy at my desk, it is the 'Copying Prohibited' slab, used from 1995-1998.
Is interesting, Thanks.

Cert numbers are generated randomly every day; they are not a continuous sequence. Of course the cert numbers for a submission are sequential and are likely sequental for the entire day only.
