The unique composition of the coin (low-grade steel coated with zinc, instead of the previously 95%-copper-based bronze composition) has led to various nicknames, such as wartime cent, steel war penny, zinc cent and steelie. The 1943 steel cent features the same Victor David Brenner design for the Lincoln cent which had been in use since 1909.
A copper-zinc voltaic pile. The penny battery is a voltaic pile which uses various coinage as the metal disks (pennies) of a traditional voltaic pile. The coins are stacked with pieces of electrolyte soaked paper in between (see diagram at right). The penny battery experiment is common during electrochemistry units in an educational setting.
After the outbreak of World War II, the demand for copper rose as it was used in ammunition and other military equipment. The US Mint researched ways to reduce or eliminate the usage of copper in cent production.
An elongated coin (also known as a pressed penny or smashed penny) is a coin that has been flattened or stretched, and embossed with a new design. Such coins are often used as commemorative or souvenir tokens, and it is common to find coin elongation machines in tourism hubs, such as museums, amusement parks, and natural or man-made landmarks .
The zinc 5 Reichspfennig coin was minted by Nazi Germany between 1940 and 1944 during World War II, replacing the bronze-aluminium version, which had a distinct golden color. It was worth 1/20 or .05 of a Reichsmark , the same ratio of a modern-day five-cent piece (nickel) to one USD.
Challenge coins are moderately inexpensive to design and produce. There are two basic processes by which to manufacture: zinc-alloy castings or die struck bronze. Zinc alloy castings offer the advantage of low cost. Zinc casting also allows more flexibility in design like cutouts found on spinner coins or bottle opener coins. [31]
This leads to the possibility of smelters taking coins and melting them down for the scrap value of the metal. Pre-1992 British pennies were made of 97% copper; but as of 2008, based on the price of copper, the value of a penny from this period is 1.5 new-pence. Modern British pennies are now made of copper-plated steel.
