T206Collector...using Demmitt and O'Hara populations as a benchmark is a very good idea.
But, I think that much more than 10% of all Demmitt and/or O'Hara owners do not have 500+. My guess is there are a lot of folks that recognize the relative scarcity of Demmitt and O'Hara, knocked those ones off early, and now are climbing up the Monster Mountain.
I only have 35 unsigned (and 26 signed) T206 cards left from my halcyon days in the top 4 of the SGC set registry, but I am holding tight to my Plank, Magie, Demmitt and O'Hara for when I exhaust my autographed T206 avenues and begin the long slow trudge up the Monster Mountain again.
