Six game-model hats from various eras of Mets history make up this amazin' lot. The oldest is an early 1960s McAuliffe with "34" written under the brim (Dave Hillman and Jimmy Piersall wore that number in the early days of the franchise). The rarest is a pillbox style by New Era that was used during a handful of games in 1976. There's an early 1980s New Era and three different 1990s models, all of which are unused.
