Mike (18colt)I agree -- Demmitt, St. Louis right below O'Hara.
I would flip-flop Magie and Plank. For every Plank you see on eBay, there are at least 3-5 Magie's for sale.
Anyone remember when Plank had a price guide value of half of the Wagner (I think it was as late as the 1970s)? How about close to equal (I think it was as late as the 1950s)? I'd argue that the number of Plank cards and the number of Wagner cards are closer than many experts believe. The legend/supposed story behind the Wagner leads to its mystique and rarity.
Anyway, it was mentioned before on a prior post, but is this a list of "rarity" or "scarcity" (virtually the same thing except that scarcity involves a demand aspect whereas rarity does not involve demand)? 
Nice idea for a list!
