## Abstract

In furtherance of the U.S. Mint's efforts to improve the environment, reduce energy consumption and enhance workplace safety and efficiency, the Mint wishes to discontinue melting and instead employ mechanical means to destroy mutilated coins. These mechanical means cannot be used to process fused or mixed coins, which represent a very small percentage of the coins redeemed annually by the Mint. Accordingly, by this amendment the Mint will also discontinue accepting fused or mixed coins for redemption, and require that all bent or partial coins submitted for redemption be separated by denomination in order to be acceptable.
