The United States Mint has issued the first biennial report to Congress required under the Coin Modernization, Oversight, and Continuity Act of 2010. The report includes an analysis of the production costs for each circulating coin, the findings of an alternative metals study, and Mint's recommendations with regards to potential changes in coin composition.
After a "thorough and meaningful" research and development study that took nearly two years to complete with an outside consultant, the US Mint has indicated that additional work is required before recommendations can be made for any specific changes in coin composition of methods of coin production.
Steam corrosion tested one cent trial strikes on aluminized steel
Wear tested five cent trial strikes on unplated copper alloy
