One of the most valuable baseball cards in the hobby and the third most valuable card in the ultra-popular T206 set this card of Hall of Fame pitcher "Gettysburg Eddie" Plank is one of the best-recognized cards outside the hobby proof of its iconic nature. "Iconic" is a term that gets thrown around quite a bit in this hyperbole-filled hobby but a T206 Eddie Plank is certainly worthy of the description.Considered one of the "Big Four" in the T206 set the Plank is so rare and valuable that most collectors consider the set complete without it. However the card is a part of the set as it was issued in the Sweet Caporal 150 series (with Factory 25 and 30 backs) as well as Sweet Caporal 350 Factory 30. After this series was distributed no additional Plank cards were printed. Today the Plank can only be found with Sweet Caporal 150 (Factory 25 and 30) Sweet Caporal 350 (Factory 30) and a small number of hand-cut Piedmont 150 backs. The Planks with the Piedmont 150 backs however were never actually distributed in packs.Many theories have been postulated about why the Plank is so rare with perhaps 100 copies in existence. Early hobby scholars suggested that the printing plate was broken or damaged a theory that was disproven as T206 researchers began to understand more about the printing of the different series. Today nobody really knows why as the rarity of the Eddie Plank card remains a mystery - that Plank is a Hall of Famer and one of the greatest pitchers of his era simply adds to the card"s mystique.The outstanding T206-related website T206Resource.com remains our "Go To" website for all things T206. The managers of that site have been working on tracking the sales of various T206 Planks in the hobby over the years which enables us to glean quite a bit of information on the cards. They have at this point identified 55 different Planks that have changed hands in recent public sale - roughly half the Planks in existence. Of those cards 30 were issued with the Sweet Caporal 350 back (the same back advertisement featured on this example) 12 with Sweet Caporal 150 backs four with Piedmont 150 backs and an additional 9 where the back cannot be determined by the scans published because the card is either ungraded or the back is not noted on the grad
