Gino’s Pocket Counter


This small and very simple key-driven adding machine has three white plastic keys and a plastic frame. A window below the first key is marked cents. Pushing the plastic key above it rotates a disc below with the digits 0 to 9 on it by one unit. The window below the second key is marked dimes. Pushing this key rotates a disc similarly marked. The third window is marked dollars. There is a carry from the first column to the second and from the second to the third. Pushing the key above it rotates a disc marked from 0 to 19. Repeatedly pushing another white key on the right side zeroes the instrument.

The instrument is marked: Gino’s {/} FREEDOM OF CHOICE. It is also marked: JAPAN. It is also marked: POCKET COUNTER.

Judy Wallace, the mother of the donor, used it in and around Cockeysville, Md., in grocery stores during the 1970s.
