Of course it's important to review Scot Reader's estimates on the no. of T-206 cards that have survived, then look at the PSA registry for slabbed T-206s.
Probably only the more expensive or valuable T-206s have been slabbed, so you would expect more low grade cards to be unslabbed. From the registry information you could make an educated guess at the raw card distribution.
