Good topic,i was thinkin' of starting a tread on this myself to get some answers to the grades i have encountered.
I sold all my extra 15th cards as NM-MINT 7''s on average by my grading standard and the seller sent them in to PSA and i was happy to see later on e-bay that they all came back very close to my estimates.
Now on the flip side i still wonder why i see cards with allot of yellowing/oxidation that grade NM.
I have seen 2 of the same cards in the same condition come back with the EXACT same grade one was white and bright and the other very oxidized and yellow.
Miscuts and o/c's that still grade very high,they should be down graded to EX in my opinion if more then 10% o/c...i think the rule is VG+ at best if the cut touchs the black boarder..?
I'm still waiting to see a graded card that was popped open and re-summited,,,so that should be intresting.
Last question is...what's up with all the split grades now?..
all i see is "EX-NM" on everything,,,does that mean it would be NM if not for a minor EX flaw...kinda seems to make grading a little useless.I see this on e-bay all the time...oh ,,it would grade Mint if not for this bent corner..
