How do they arbitrarily define what a "catalog" is? In todays electronic world the
trading card database is as much a "catalog" as any other although it does not list values - which shouldn't matter as PSA has their SMR! The inconsistency has been rampant in numerous ways. Yet, they continue to be the 800lb gorilla largely due to the registry and large barriers to entry. I too have tried to have a number of items added only to face the same frustration that has been shared in this thread.
As an aside, I like Beckett's grading model the best with the 4 subgrades and then the averaged final grade - it allows collectors to prioritize elements of condition subjectively important to them.
