2012 Topps Triple Threads Baseball is now live and like last year Topps has gone the gimmick route and continued the American History relic cards.
Last year we saw 2 mythological folklore characters, Pecos Bill and John Henry, along with Norse/Viking explorer Leif Ericson though I am not certain how Ericson is directly connected to American history because he landed in what is now part of Canada. This year Topps did go with three real personalities that are part of American history with Davy Crockett, Daniel Boone and Casey Jones.
These cards are considered bonus cards, so they are not taking the place of a guaranteed hit.
Currently there is a Davy Crockett card up for auction at $599.99 with 2 declined offers. Recently a Daniel Boone card and a Casey Jones card sold for $175 each. There is also a 2011 John Henry card up for auction at $30.01 with 3 days left.
