My most valuable card is a 1952 Topps Mickey Mantle.I also have many t206 andt205 cards, but my favorite card in my collection is a E90-1 American Caramel Joe Jackson.
I have most of the 1965 Topps set, Joe Morgan rookie, Pete Rose, Roberto Clemente. I have never really gotten any valuable cards in packs except for two. I pulled a SP Chirography redemption of Sosa/Griffey/Giambi in 2003 and sold it for $400. That same day I pulled a 1999 Josh Hamilton Topps Traded rookie auto. I have still have that Hamilton card.
