Here come the new coins:

Can George Washington and Thomas Jefferson succeed where Susan B. Anthony and Sacajawea failed? The U.S. Mint is hoping America's presidents will win acceptance, finally, for the maligned dollar coin.

The public will get the chance to decide starting in February when the first of the new coins, bearing the image of the first president, is introduced.
Washington, John Adams, Thomas Jefferson and James Madison are scheduled to grace the coin in 2007, with a different president appearing every three months.
