The new 2010 Native American $1 coin goes on sale this Friday at noon Eastern Time. A roll of 25 coins will cost $35.95 through the U.S. Mint.

The theme of the coin is "Government-the Great Tree of Peace." The tails side features an image of the Hiawatha Belt with five arrows bound together, along with the following inscriptions: UNITED STATES OF AMERICA, $1, HAUDENOSAUNEE and GREAT LAW OF PEACE.

The head side features the familiar image of Sacagawea, the Shoshone woman who helped explorers Lewis and Clark.

Congress authorized new designs for the coin through the Native American $1 Coin Act of 2008 . The tails side will celebrate the contributions of Native Americans to U.S. society and recognize important Native Americans. Sacagawea will remain on the front of the coin.
