FYS"A 1935 National Chicle Bronco Nagurski graded psa 9 sold for $85k a few years ago on Ebay.
I was also told by Gilbert Porter at the national that BMW cards reportedly sold his psa 9 N172 Kelly for $100k. Can you confirm this Mike or Brian?"
Not sure about the Kelly, but the Nagurski was actually an SGC 96 and I believe it is the highest price paid for a football card. BMW was the sellers of the Nagurski.
