notes: label: Description
content: This key-driven counter has four plastic keys, a plastic case, plastic number dials, and metal springs. There are four keys across the top and four number dials in front. Totals of up to 9999 can be indicated, although the carry appears only to work from one column to the adjacent column. The columns are labeled from right to left "CENTS" "DIMES" "DOLLARS and "10 DOLLARS". Pushing any of the three right keys increases the corresponding digit below. Pushing the leftmost key decreases the 10 dollars amount by one unit.
