The submission where this comes from also included another PSA 10 1st ed. Lugia, cert number is 23878947. Good luck finding rest of the info, I think lists like this are good resource for other high demand set cards.
I had some spare time and so I decided to play around with the certification look up and check if there are some sequential certs and I have found: 18756826
26450128 is a funny one, 3 certs down and 2 certs up do not exist in the psa database (does that mean the cases were cracked and that the labels were sent in?)
26569326, this cert has got 6 psa 9 lugias surrounding it, nice submission!
I came to number: 27068663 after which I had to redo the captcha and I could not for the life of me complete the new captcha, so I am a robot. Well one new cert so only 4 left now!
The “No Grade” term is used when an item cannot be graded by PSA for a variety of reasons. For example, PSA will not grade items that bear evidence of trimming (N1), restoration (N2), recoloration (N3), questionable authenticity (N4), altered stock (N5) or cleaning (N7). In the event that PSA rejects an item for any of these reasons, it will be returned not encapsulated, however the full grading price is still charged, as the determination to reject a card requires review by PSA’s authenticators and graders. PSA will also not grade items that do not meet the minimum size requirement (N6), were miscut by the manufacturer (N8), or items we do not grade due to being an obscure issue or not fitting in our holders (N9). Items that receive N6, N8 or N9 results will not be charged grading.
