I don't find it listed in any of the "maverick" references I have. What town was close? That would be the best place to start researching. Bakery tokens like this were used in various ways, but the most common was where the bakery would sell a "baker's dozen" (13) loaves of bread for the price of 12. Of course the consumer wouldn't want them all at once, so the bakery would give them tokens for future purchases. Then a child could be sent to the bakery with a token in hand and there would be no worry about the kid stopping at the candy store and spending the money there. Or, where the bakery delivered, the proper amount of tokens could be left on the back porch for the deliveryman who would leave the requested number of loaves. All of this was popular in the 1910-30 era. When the bakery closed, the tokens were possibly disposed of by throwing them far out into the lake. Over time, this one migrated closer in.
