RichardPeter - I do not believe any T215 Pirate Cobb has been found to date, although many have speculated that it could exist.
Ted - I do not quite understand your question about what "population" has to do with anything. As Dan said, population is everything. You are trying to verify if any more than 4 Sov 460s exist. There is discussion if there are 12, 13 or 14 Ty Cobb backed cards that exist. This is all about population and rarity. We are not talking about graded population. Just population. That is the whole point of your thread.
As for T213s, I do not believe any of the 3 issues should be considered in this rarity discussion (single digit population). Clearly Type 1 is the toughest of the 3 series, but I have owned 2 examples myself. They are not in the ballpark.
