aluminum cents from wiki,
"1974 aluminum cent from the SmithsonianDuring the early 1970s, the price of copper rose to a point where the cent almost contained more than one cent's worth of copper. This led the Mint to test alternate metals, including aluminum and bronze-clad steel. Aluminum was chosen, and over 1.5 million of these cents were struck and ready for public release before ultimately being rejected. The proposed aluminum cents were rejected due to two factors. Vending machine owners complained the coins would cause mechanical problems. Pediatricians and pediatric radiologists pointed out the radiodensity of the metal inside the respiratory and gastrointestinal tracts was close to that of soft tissue and therefore would be difficult to detect in a roentgenogram.[1] About a dozen aluminum cents are believed to still be in the hands of collectors, although they are now considered illegal, subject to seizure by the Secret Service.[citation needed] One aluminum cent was donated to the Smithsonian Institution."
Some of these are rumored to still exist in private hands. They are of course illeagle to own.
