The 1966 Topps baseball card set features 598 standard size cards, which measure 2½” by 3½”. The only subset for the 1966 Topps baseball cards is the league leaders (215-226). The high number series (523-598) is more difficult and expensive to collect. This set has been considered undervalued and underrated for a longtime, but it does have some gems to be discovered. It has a design that tends to get overlooked in favor of the bolder designs of other Topps sets in the 1960, but to devoted collectors, the 1966 set holds a special allure for basic but classic looks. While it lacks some of the high powered rookies, it does have a few rookie standouts like Jim Palmer, Fergie Jenkins, and Don Sutton.
