1972 O-Pee-Chee/OPC #425 Ken Singleton (Mets)

Fleer was prevented from using current players by Topps' exclusive rights, so they issued their Baseball Greats set using retired players, managers, executives and the two league commissioners. Luckily Fleer had their own exclusive rights deal with Ted Williams, who quickly became the most in demand card in the set. Unfortunately the weak card design and retired players made it a giant dud with kids and the product was not well received.

There are very scarce variations with Joe Tinker,Eddie Collins & Lefty Grove fronts, all with #80 Pepper Martin backs. They are usually found cancelled or hand-cut from sheets. Likely Pepper Martin's card was pulled due to contract issues. The variations are not considered part of the complete set.

Collectors say "They are official documents of a particular game, so they are absolutely historically relevant. The manager, he was the general in the war. Imagine owning Eisenhower's list of who he wanted to go into battle, and then he signed it !!! Imagine what that would be worth?"

The first dugout lineup cards were seen around 1960. Along with lineup cards, most ended up in the trash after games, making them quite rare today. MLB saw the light and started marketing them directly in the 2000's.

Astronomical prices have been paid for cards from special games.
$165,010 for the Red Sox dugout lineup card from Game 4 of the 2004 World Series.
$138,000 in 2007 for 1st ever All-Star Game batting order cards.
$ 40,000 for batting order cards and the pen used to fill them out from Cal Ripken's 2,130th & 2,131st games.
