The Coin Coalition is an organization supporting the elimination of pennies and dollar bills from U.S. currency. It is funded by vending machine companies, video arcade owners, and the soft drink industry, who all have an interest in eliminating maintenance costs associated with dollar bill validators.

Although copper miners and other interest groups backed the Coin Coalition on this issue, they were unable to match the influence of Save the Greenback, a rival organization supporting continued dollar bill production.
