About this opportunity
The Department of the Treasury is seeking a contractor to develop an anti-tarnish treatment for silver numismatic alloys at the San Francisco Mint. The primary objective is to create a monolayer coating that prevents corrosion and tarnishing of coin blanks while maintaining the minting process's integrity. The project will involve multiple testing phases, including initial recipe modification, determining optimal chemical application, and conducting stamping trials to assess potential adverse effects. A comprehensive safety and environmental review will be conducted in collaboration with California regulatory bodies to ensure workforce health and compliance. The full evaluation will include onsite testing at the San Francisco Mint, third-party laboratory corrosion inhibition testing, and an accelerated shelf-life assessment of the treated coins.
The contract opportunity is not designated with a specific set-aside and falls under the NAICS category of Paint, Coating, and Adhesive Manufacturing (NAICS 3255). The pre-solicitation notice was posted on April 4, 2025, with a response deadline of June 28, 2025, suggesting a potential project timeline of several months. While specific award values are not disclosed, the contract will involve comprehensive testing processes, including third-party lab assessments and packaging evaluations, which will be conducted at the expense of the US Mint. The project's scope indicates a sophisticated technical requirement for developing a specialized anti-tarnish treatment that maintains the quality and preservation of numismatic silver alloys. The contractor will need to demonstrate technical expertise in surface treatment technologies and an understanding of mint-specific metallurgical requirements.

Develop a monolayer for Numismatic Multiple Alloys
The initial phase of testing will determine if and how much the burnishing recipe used at San Francisco must be modified. Additionally, the initial phase of testing will determine how much of the anti-tarnish chemical should be applied. Lastly, a stamping trial will be incorporated in order to determine if any adverse effects are seen when stamping the blanks.
Simultaneously a safety/environmental review must be performed by the San Francisco Mint with California regulatory bodies as external stakeholders. Any concerns should be addressed in order to meet regulations and ensure the health and safety of the workforce.
Onsite testing and validation should occur at the San Francisco Mint as the final phase. This would include processing blanks according to the recommended recipe, testing the blanks at a 3rd party lab for corrosion inhibition (at the expense of the US Mint), stamping treated blanks to ensure the coining process and finally packaging the coins and performing an accelerated shelf-life test to ensure corrosion and tarnishing inhibition for final goods (at the expense of the US Mint).
