Американские телефонные жетоны фирмы Goetz. Использовались в начале 20-го века.
Before there were telephone cards to collect and use, telephone tokens were a widespread medium of exchange for people wanting to talk with someone across the ocean or across the street. The first major evolution in telephone tokens occurred in 1907 when a Chicago druggist named Henry Goetz patented a round token with a cut in it running from the center to the edge. The token could only be used in machines with an attachment over the coin slot that admitted tokens of the same shop. This innovation came about mainly because store owners and the Chicago Telephone Company did not sell tokens, individual shopkeepers and tavern owners did.
