National Cash Register, Class 51
DESCRIPTION
In the 1950s Americans increasingly bought groceries in supermarkets, which served large numbers of customers. Consumers selected their own goods, and took them to a clerk who rang up sales. To make transactions as efficient as possible, the National Cash Register Company introduced machines that dispensed coins automatically, avoiding time and errors associated with making change. This change-making cash register went on the market in 1954, with a new model in 1958. This example was given to the Smithsonian by NCR in 1959, on the occasion of the seventy-fifth anniversary of the company.
