When did the us stop making full cooper pennies?
The United States stopped producing full copper pennies in 1982. Prior to that year, the pennies were made of 95% copper and 5% zinc. Starting in 1982, the composition changed to 97.5% zinc and only 2.5% copper, resulting in a much lighter coin. This change was primarily due to rising copper prices.
When did they stop making pennies with copper?
US Pennies were made of 95% copper (with the exception of the 1943 steel cent) from 1864-1982. Midway through 1982, the cent switched to copper plated zinc. So any penny dated 1983-present is just copper plated zinc. However a coin dated 1982 could either be 95% copper or copper plated zinc. A copper coin should weigh about 3.11 grams while the zinc pennies are lighter at about 2.5 grams.
When did the us stop making copper pennies?
They stopped making copper pennies in 1982. There are some 1982 pennies that are 95% copper and some that are not. 1983 pennies that are 95% exist but are rare and are collectors items.While the above statement would seem to be correct, it is, however, not completely true. The U.S. has never stopped making copper pennies, or pennies with some copper content, except in 1943, when they were made of a low-grade carbon steel and coated with zinc (having a grey color); this change was due to the need for copper and brass during World War II. These 1943 wartime pennies are commonly referred to as "steel" pennies. They contain NO copper...More correctly, 1982 was the last mint year for 95% copper cents. Since mid-1982, the newest (current, as of 2012) composition for U.S. one-cent coins ("pennies") has an inner core alloy of 99.2% zinc with 0.8% copper, with the coin balance as an outer plating of pure copper, for a total coin composition of 97.5% zinc and 2.5% copper. These current pennies are commonly called "zinc pennies", due to their heavy-majority zinc content, even though they do still contain some copper. The composition of U.S. pennies from mid-1864 to mid-1982 was an alloy of 95% copper with either 5% tin-and-zinc ("bronze" pennies) or 5% zinc ("brass" pennies). Before that, the composition was an alloy of 88% copper with 12% nickel from mid-1857 to mid-1864 (the only time any U.S. pennies ever contained nickel), and, initially, from 1793 to mid-1857, the first U.S. pennies were made of pure (100%) copper.Since the first U.S. one-cent coins in 1793, U.S. pennies have always contained at least some copper, except, again, in the singular case of the year 1943, the so-called "steel" pennies.Therefore, the most correct answer to the question is either:(1) the U.S. has never stopped making copper pennies, except in 1943; or(2) 1943 is the only year the U.S. stopped making copper pennies, or any pennies with NO copper in them.Hope this helps!
