BobThe video was interesting and I think it is just great that the young man is so happy with his collection and has used it as a learning tool. That said, his 525,000 cards are probably all from the last 10 years, Topps, Donruss and UD (I am guessing here) and any comparison of collections with the aforementioned collectors isn't appropriate. A guy might have 500,000 comic books which are all Archies and Shogun Warriors from the 90's, but I think this wouldn't compare with a guy whose collection is 50,000 books but has complete runs of Batman, Action, Adventure and All-Star comics, etc from the 40's. Apples and oranges.
So "biggest" collector wouldn't be the guy with the most cards necessarily.
There are also some huge and valuable collections out there which are totally under the radar. Old guys who never mastered the internet and stored their collections decades ago in the attic or basement. Perhaps these cards will begin to surface in the next 5-15 years as the Grim Reaper draws near, as it does for all of us eventually...
