The Roosevelt dime is the current ten-cent piece of the United States, displaying President Franklin D. Roosevelt on the obverse. Authorized soon after his death in 1945, it has been produced by the Mint continuously since 1946 in large numbers. Roosevelt had been stricken with polio, and was one of the moving forces of the March of Dimes. The ten-cent coin could legally be changed by the Mint without the need for congressional action, and officials moved quickly to replace the Mercury dime. Chief EngraverJohn R. Sinnock prepared models, but faced repeated criticism from the Commission of Fine Arts. He modified his design in response, and the coin went into circulation in January 1946. The Mint transitioned from striking the coin in silver to base metal in 1965, and the design remains essentially unaltered from when Sinnock created it. Without rare dates or silver content, the dime is less widely sought by coin collectors than other modern American coins. (Full article...)

A two-shilling note of the New York pound, a currency used in the Province of New York.

This note was signed by John Cruger Jr., then the speaker of the New York assembly.
