How does PSA decide what cards to grade?

[hcv123]

Is they throw darts and grade when one hits ( of course it will automatically be graded a 1 with the dart hole!)

Seriously - the will grade Clemente Jay publishing issues from 1957 forward, but for some reason refuse to grade the rarest 1956.

They include bazooka singles, panels and boxes as 3 separate line items in registry sets, but refuse to differentiate Salada 180 and 200 variations as separate items. Similarly don't differentiate between 69 Nabiso Wide and Narrow border cards.

They have people cut up complete transogram boxes so they can "grade" the 1/2" X 1/2" "side panels"

They just started grading Coke bottle caps, but are apparently lumping all the different soda flavors and different years (1967 and 1968) into one generic "1967-68" heading

They recognize some variations and not others.

I have requested many items to be added over the years - many have been and some have not (I have had no luck pointing to the "Trading Card Data Base" as a reference source for them). One word comes to mind with my experience - inconsistency.

They "recognize" some Clemente team issues but not others (getting quite a few of them wrong I might ad).

Good luck getting your item added.
