I'm new to submitting for grades. I have some 70's basketball cards that have been kept in close to mint condition through the years, one owner passed down to me, kept in the same top loaders for at least 30 years. Raw range of $20-80, nothing extremely valuable. Almost all of them have terrible centering, but like I said, are otherwise very sharp. Should I grade, and what type of grade would I expect? For sub-grades, I'd expect a six or below. So how would they grade? Lets say center was a 6, but the other 3 were 9s. 33/40=8? Is that how it works?
I'm assuming that if I want to sell these on ebay and I'm in no rush, then it would definitely make sense to grade, correct?
Thanks for the help!
