CHEYENNE, Wyo. (AP) -- Wyoming U.S. Sen. Mike Enzi has joined four other senators in promoting the replacement of dollar bills with coins.
Enzi joined fellow Republican Sens. John McCain of Arizona and Tom Coburn of Oklahoma and Democrats Tom Harkin of Iowa and Mark Udall of Colorado in introducing legislation to promote the $1 coin as a way to save money and reduce the federal deficit.
Enzi says making the change to dollar coins is one step toward fiscal responsibility.
A Government Accountability Office study estimates the savings of moving from paper to coin at between $200 million and $500 million a year.
Supporters of the change say the $1 coin is also environmentally friendly because the coin will last an estimated 30 years while a $1 bill lasts about three years.
