I have been working on an AU checklist from a Panini basketball release from 2021-22. The set has been out coming up on 5 months. The AU set has letters instead of numbers so this has required having to search the cards online to get the actual card numbers. Panini only lists them as numbers on their checklists.
There are 2 cards I have not been able to find as of yet. I have been checking most mornings for the 2 cards. Neither the base version or any of the parallels seem to have surfaced online. This leads me to wonder whether they even exist, whether they are redemptions, or whether anyone even cares enough about these cards enough to list them for sale. Maybe they just haven't been pulled yet after 5 months.
My question- Is there a protocol or a timeframe on when a mostly complete checklist can be uploaded? Or is this to be avoided completely? I have seen other threads mentioning that after some time TBA may be acceptable for the card numbers on some of these Panini checklists.
Since I haven't found these 2 cards I am looking for some guidance.
