- The 1974 aluminum cent was a one-cent coin proposed by the United States Mint in 1973. It was composed of an alloy of aluminum and trace metals, and it was intended to replace the predominantly copper–zinc cent due to the rising costs of coin production in the traditional bronze alloy. Of the 1,571,167 coins struck in anticipation of release, none were released into circulation. To encourage congressional support for the new alloy, the Mint distributed several examples to US Congressmen. When the proposed aluminum cent was rejected, the Mint recalled and destroyed those coins. However, despite the recall, a few aluminum cents were not returned to the Mint, and those coins may remain at large. One example was donated to the Smithsonian Institution, while another was alleged to have been found by Albert P. Toven, a US Capitol Police Officer. A 1974-D specimen was found in January 2014 by Randall Lawrence, who said it was a retirement gift to his father, Harry Edmond Lawrence, who was Deputy Superintendent at the Denver Mint. Randall planned on selling it in a public auction, but the Mint demanded its return, saying that the coin was never authorized for release and therefore remains U.S. Government property. Lawrence (and his business partner at their coin store, Michael McConnell) ultimately surrendered the coin when the Mint showed that the aluminum cent had never been authorized to be struck in Denver, and there was no evidence that the coin had been a gift of any kind.

- 1974年铝制一美分是美国铸币局1973年提倡的一种1美分硬币。这是一种由铝合金和微量金属铸造的硬币。由于使用传统铜合金的铸造成本的增加，它计划被用来替换铜锌合金的硬币。 1,571,167枚硬币被提前铸造，但没有一枚进入流通。样币被送到美国国会，希望能够获得议员对于更换合金这一计划的青睐。当铝制硬币提议被否决时，铸币局召回并销毁了样币。据信仍有极少量的铝制硬币没有被铸币局回收，其中一个例子就是捐赠给了史密森学会，另有一枚据称从一名美国国会警察那里发现。但自从美国特勤局被派给扣压全部样币的的任务后，这些硬币的合法性受到怀疑。 (zh)
