2010-D Jefferson Nickel

The United States Mint today announced that it is requesting public comment from all interested persons on factors to be considered in conducting research for alternative metallic coinage materials for the production of all circulating coins.

These factors include, but are not limited to:

  • The effect of new metallic coinage materials on the current suppliers of coinage materials
  • The acceptability of new metallic coinage materials, including physical, chemical, metallurgical and technical characteristics
  • Metallic material, fabrication, minting, and distribution costs
  • Metallic material availability and sources of raw metals
  • Coinability
  • Durability
  • Sorting, handling, packaging and vending machines
  • Appearance
  • Risks to the environment and public safety
  • Resistance to counterfeiting
  • Commercial and public acceptance
  • and any other factors considered to be appropriate and in the public interest

The United States Mint is not soliciting suggestions or recommendations on specific metallic coinage materials, and any such suggestions or recommendations will not be considered at this time. The United States Mint seeks public comment only on the factors to be considered in the research and evaluation of potential new metallic coinage materials.

The recently enacted Coin Modernization, Oversight, and Continuity Act of 2010 (Public Law 111-302) gives the United States Mint research and development authority to conduct studies for alternative metallic coinage materials. Additionally, the new law requires the United States Mint to consider certain factors in the conduct of research, development, and solicitation of input or work in conjunction with Federal and nonfederal entities, including factors that the public believes the United States Mint should consider to be appropriate and in the public interest.

Comments must be submitted on or before April 4, 2011. Interested parties may submit written comments by any of the following methods:
