This is a generic amusement token. In Alpert and Smith's _Video Arcade, Pinball, Slot Machine, and Other Amusement Tokens of North America_, 1st edition, 1984, this token is located in the Phrases section (amusement tokens without names or initials, but having phrases related to amusement). I believe this to be the 21mm brass variety with center hole (also nickel plated brass, white metal, and lead varieties). There are varieties, as in use of different numbers, as well as a blank reverse. Value in this 1984 ref. was listed at $.05. The letter sequence used to identify this token is MOA.
