Who is the most collected player of all time?

And here I was trying to figure it out based on adding in set collectors and general collectors.

Nearly everyone wants a Ruth card, but unless it's one of the modern ones there aren't that many around.
The more current players have more cards, both more different cards, and more cards total.

I'd have to go with Mantle. There was that whole insert set with one for each home run. I think there was a similar insert for Bonds though....

And for total cards, Ryan was in all those massively overproduced sets in the late 80's and early 90's....
