I should be getting my Ludkins UK May 2020 submission back tomorrow. They were kind enough to let me know one of the certificates up-front so I could find all the grades. The submission was registered by PSA on 31st July 2020 and the cards have 487xxxxx certificates.
I know from the PSA pop report parsing I do that @blackbelt172 's recent (presumably walkthrough) returns were graded around 2nd May with 614xxxxx certificates and mine were graded 3 weeks later on 23rd May. This implies that PSA’s backlog still consists of multiple millions of cards.
This is also interesting in that blackbelt’s PSA 10 unlimited E1 Pichu was graded 3 weeks before mine, yet mine has a significantly lower certificate number. If anyone here places higher value in cards they believe to be the first graded copy you may want to think twice if it has a post-4xxxxxxx certificate.
Considering PSA has only graded 1.73 million Pokémon cards in total I think the 12.7 million gap between 487xxxxx and 614xxxxx really emphasises firstly how small of a percentage Pokémon makes up in the overall number of cards PSA grade and secondly just how many cards have been submitted in the past 10 months.
