The 587-card 1964 Topps set is collectible for a number of reasons. While it may not exhibit the difficulty of the 1962 or 1963 Topps set, this Topps issue is deceptively tough. The orange/pink reverse is very susceptible to chipping and the trivia "rub-off" question is often tampered with. Both obstacles can cause condition problems. In addition, the front was often cut off-center with varying degrees of print quality. Advanced collectors will notice that many of these cards are found with varying appearances. Some have nice registration and white borders while others are found with blurred photos and "dirty" or gray looking borders. As far as keys are concerned, the Mickey Mantle and Roberto Clemente cards immediately come to mind, the Clemente residing in the tougher high-number series. Other interesting cards like the Phil Niekro rookie and various combo cards that feature the great stars of the day like A.L. Bombers (Mantle, Maris, etc.) and Tops in the N.L. (Aaron and Mays) are also included. All in all, this is a nice set that offers a slightly more affordable alternative to some of the other sets of the decade. To read an in-depth article, click here.
