WASHINGTON — A plan to raise interest in the Gold Dollar coin featuring Sacagawea has been stamped with Congress’ approval, but the Santa Fe artist who helped make the original thinks it’s “silly.”

Under a new law, the U.S. Mint will start reissuing the coin featuring Sacagawea, the Shoshone woman who guided Lewis and Clark, in 2009. On the coin’s reverse side, the mint will replace a soaring American eagle with depictions of other famous American Indians or American Indian events.

The Treasury Department has yet to pick the designs, but some suggestions in the law include a World War II Navajo Code Talker, Olympic athlete Jim Thorpe and the Pueblo Revolt of 1680, whose leader, Pop‚, already has a statue in the Capitol.
