Bat Coins - Sharkey

Transogram issued these as components for their 1966 Bat Coins game, a Batman-themed coin collecting set aimed at capitalizing on the ABC television series that had premiered in January of that year. The show's runaway popularity in its first season triggered a licensing frenzy, and Transogram was among dozens of manufacturers scrambling to put Batman-branded products on shelves before the craze cooled — which it did, rapidly, by 1968.

Sharkey is one of the villain characters featured across the set. Not a Batman canon figure of any particular significance, the name likely refers to a generic adversary invented for the game rather than a comics or television source.
