Missouri sales tax reciept token?

[GBRD]

Hi everyone!!!! Found this today. Obverse and reverse sides are the same and say missouri sales tax reciept. There is also an outline of the state, with a 1 in the middle of the outline. Might be made out of aluminum. Would anyone have any information or history?
