Dollar coins can be purchased from a local bank branch or the United States Mint website. As of 2015, the United States Mint is offering Presidential and Native American one dollar coin programs.
The United States Mint offers a selection of Presidential one dollar coin sets from the last few years. Individual Presidential one dollar coins are also available in 25-coin rolls, 100-coin bags and 250-coin boxes. The Presidential Coin Program was launched by the United States Mint in 2007. Over a ten year period, the mint is releasing one dollar coins featuring each US President. Every year, four new Presidential coins are released.
Like the Presidential coins, Native American one dollar coins are sold by the mint in the same quantities of rolls, bags and boxes. The Native American coins feature Sacajawea, the guide for the Lewis and Clark expedition, on the obverse side. The reverse side features a new design each year that is selected by the Secretary of the Treasury in cooperation with the Congressional Native American Caucus of the U.S. House of Representatives, the U.S. Senate Committee on Indian Affairs, the National Congress of American Indians and the Commission of Fine Arts. The 2014 coin features a design that exemplifies Native American hospitality, in which a man is offering his pipe and his wife is offering corn, gourds, fish and roots.
