I am fairly new to collecting this set and wanted to know more about the more rare backs and how that affects value.
I was browsing ebay and saw
http://www.ebay.com/itm/1909-11-T-20...p2047675.l2557
this card sell for 10 times more than what a graded copy of a caporal/piedmont back sells for. Do the Lenox backs make basically any card substantially more valuable like this? What are other examples of this? And is it possible for any card to have any back? I'm sure there isn't a Lenox Wagner going around, but it is theoretically possible?
