The latest projection from the Government Accountability Office on the potential savings from switching to dollar coins entirely comes as lawmakers begin exploring new ways for the government to save money by changing the money itself.
The Mint is preparing a report for Congress showing how changes in the metal content of coins could save money.
The last time the government made major metallurgical changes in U.S. coins was nearly 50 years ago when Congress directed the Mint to remove silver from dimes and quarters and to reduce its content in half dollar coins. Now, Congress is looking at new changes in response to rising prices for copper and nickel.
At a House subcommittee hearing Thursday, the focus was on two approaches:
—Moving to less expensive combinations of metals like steel, aluminum and zinc.
—Gradually taking dollar bills out the economy and replacing them with coins.
