Included in the Hall of Fame collection are the Retroactive Hall of Fame Pins. These pins, they come in a set of two, feature inductees from past years, starting in 1990 with the inaugural year of 1936. The purpose of these pins is to honor those who were inducted before the pin program was created in 1982. The 2007 pin set features inductees from 1957 and 1964. The 1957 inductees are Sam Crawford and Joe McCarthy. The 1964 inductees are Luke Appling, Red Faber, Burleigh Grimes, Miller Huggins, Tim Keefe, Heinie Manush, and John Ward. Eventually, there will not be a need for retroactive pins, and because there are only 500 limited edition retroactive sets produced each year, these pins are extremely coveted by pin collectors. I believe that 2008 will be the last year for the Retroactive Pin Sets. The 2008 two pin set will include 1959 Zack Wheat and 1965 Jim Galvin.
