The famous 1974 aluminum cent. Although this piece is listed in the pattern books, it is technically not a pattern, die trial or experimental piece. It is really a rejected or cancelled regular issue similar to the 1964 Peace Dollar or the 1907 Rolled Edge Eagle.

During the early 1970s the price of copper was rising to the point where the penny almost contained one cents worth of copper. This led to the mint testing alternative metals. Aluminum was chosen to the point where over 1.5 million of these were struck and were ready for delivery to the public before ultimately being rejected.

The price of copper later returned to levels which made the production of copper cents profitable so that the mint would not need to change its composition until 1983.

A dozen or so of these are still believed to be in collector's hands. Rumors about at least one of these appeared in many articles in the 2001 numismatic press including the Numismatist, Coin World and Numismatic News. One has even been graded by ICG as AU58 !!

Examples were also made in bronze-clad steel J2152.

According to an article in the Numismatist and also Coin World, 66 examples dated 1975 J2155 were also struck.

It is unclear whether any of these latter pieces still exist. The Secret Service has said that it will confiscate any of these pieces should they turn up in the market place.
