How many copies of T206 exist today?

[Kidnapped18]

Have you been to a show lately? Dealers have hundreds/thousands of T206 cards in binders at the shows and they have hundreds/thousands of binders to look through. Then throw in the slabs and all the cards listed on eBay and the auction houses.

For the non SLers yes I agree that each player (minus the obvious Wagner, Plank, Magie, Doyle, Demmitt, O'Hara) has at least 1000+ cards that survived either graded or raw however for the SLers it is clear to me that none of those players have more than 750 copies that would be available.
For the SLers PSA has about 300 cards per player and SGC has about 200 cards per player when you factor in resubs, crack outs, crossovers, raw etc. I would put the number of SLers that are still existing in the 500-600 range each incl BVG, PSA, SGC and raw
So if you had 100 copies (Hindu, Old Mill, Piedmont) of a SLer say Shaughnessy then I would say you have about 20% of that card that is available.
