1977 Lincoln Cent, MS60
Struck in Aluminum
Sole Example Known

1977 1C Lincoln Cent -- Struck on an Aluminum Planchet -- MS60 NGC. 1.04 grams. One of the most famous modern mint rarities is the 1974 aluminum cent. It had a mintage of approximately 1.5 million pieces, but virtually all were melted. According to USPatterns.com, PCGS graded an example as MS62 with a weight of 0.93 grams. A typical 1977 copper cent has a standard weight of 3.11 grams. According to MintErrorNews.com, the present lot is the only known aluminum 1977 cent, and was in the collection of error specialist Fred Weinberg for "over two decades." MintErrorNews.com suggests three possible scenarios for its existence. It could be an intentionally made mint error, a pattern struck in aluminum, or a strike on a leftover planchet from the 1974 to 1975 production era of the aluminum cent. In any event, this is the only aluminum Lincoln cent that any collector can reasonably hope to own. The untoned surfaces show a good strike, satiny luster, and a few minor rim marks. The NGC insert misspells the alloy as ALUNIMUM.

A 1971-S cent struck on an unidentified foreign aluminum planchet was certified by NGC as AU58. It sold in the Heritage September 16, 2024 Error Coinage US Coins Showcase Auction #60398 for $31,200 (lot #52156).
