fkwIm sure there are more than 15 of the PC799 NL Champs cards, Thats just the number Ive seen in the last 8-10 years or so that Ive been looking for 1905-15 era single player postcards (that I can remember). I didnt really counting complete sets etc. in Major Auctions.
Some of the cards are often seen in large groups. PC799 WS Champs (I once bought a group of 15 cards on eBay), and AC Dietsche Tiger cards are seen in groups often. Even tougher cards like Grignon and Rose cards show up on eBay in groups sometimes, bring the number Ive seen far higher.
There is a group of the "$ in Shield" cards on right now, they are fairly rare overall, but this group makes them seen not so rare.
The rarest cards as far as numbers in existance are probably the Real Photo cards, like the Barr-Farnham pictured above, The Corbit Studio, and even the PC800 Coyle (Pirate Vignette) cards, etc.
