lumber mills and many other businesses. The era of 1870 through 1920 marked the highest use of "trade tokens" in the United States, spurred by the proliferation of small stores in rural areas. There were thousands of small general and merchandise stores all over the United States, and many of them used trade tokens to promote trade and extend credit to customers. Aluminum tokens almost always date after 1890, when low-cost production began. Slot machines Metal token coins are used in lieu of cash in some coin-operated arcade games and casino slot machines. Money is exchanged for the token coins or chips in a casino at the casino cage, gaming tables, slot machines or cashier stations for slot token coins. The tokens are interchangeable with money at the casino and generally have no value outside of the casino. In many jurisdictions, casinos are not permitted to use currency in slot machines, necessitating tokens for smaller denominations. After the increase in the value of silver stopped the circulation of silver coins in the United States around 1964, casinos rushed to find a substitute, as most slot machines at that time used that particular coin. The Nevada State Gaming Control Board consulted with the U.S. Treasury, and casinos were soon allowed to start using their own tokens to operate their slot machines. The Franklin Mint was the main minter of casino tokens at that time. In 1971, many casinos adopted the Eisenhower Dollar for use in machines and on tables. When the dollar was replaced with the Susan B. Anthony dollar in 1979, most casinos reinstituted tokens, fearing confusion with quarters and not wishing to extensively retool their slot machines. Those casinos which still use tokens in slot machines still use Eisenhower-sized ones. Tokens are being phased out by many casinos in favor of coinless machines which accept banknotes and print receipts for payout. These receipts, abbreviated "TITOs" for ticket-in, ticket-out, can also be inserted into the machines. In video arcades, they are also being phased out in favor of magnetic cards, which can also count how many tickets one has, allowing arcades to also do away with paper tickets.
