Lincoln pennies that were minted between 1959 and 1982 tend to be worth more since they are almost 100 percent copper, rather than an alloy. Improperly prepared dies can result in coins with a "double" image.
The most well-known was in 1955, but this also occurred in coins dated 1917, 1936, 1958, 1969-S, 1971, 1971-S, 1972 and 1995. Originally believed to be counterfeit, the government destroyed five coins before acknowledging the error.
In January 2008, a doubled die obverse uncirculated penny, red-brown in color, sold at Heritage Auctions in Orlando.
