Here’s the Frank Nagy 1909-11 T206 Honus Wagner as presented in MastroNet’s Sporst Auctions of Distinction in December 2005. GAI noted the card’s lineage on the reverse flip.
The card’s description in the catalog was pretty fluffy, which I’m not sure is ever really needed for cards of this magnitude. It sold for $456,057.
In a 2007 article about Nagy, Sports Collectors Digest shared that Nagy got the Wagner from Preston Orem in the early 1960s for $100. The T206Resource and net54 board members report that the card is now slabbed via SGC at a 1/2 grade lower of 3.
To add a bit of “Hobby Library” flair to this post, Nagy featured the card on the cover of the November-December 1962 issue of The Sport Hobbyist.
I wonder if a copy of that magazine was included when Nagy’s Personal Collection of Hobby Publications was auctioned off.
