Best Answer

In 1982 the US mint changed the composition of the penny from mostly copper to zinc which changed the weight form 3.11 grams to 2.5 grams and made the penny cheaper to make.

Do pennies have copper in them?

yes, they're made of a zinc core with a thin layer of copper plating. The plating only makes up 2.5% of the coin's weight, though.


Where do the pennies come from?

The U.S. Mint, of course. Currently cents are minted at Denver (D below the date) and Philadelphia (no letter) In the past, cents were also made at San Francisco, with an S. When the Phila. and Denver Mints are overloaded, the West Point Mint sometimes helps out. It doesn't use a mint mark letter when it makes pennies, so they look just like Philadelphia ones.


What is the last year of the copper penny?

The first copper plated zinc (U.S.) cents were struck at the end of 1981 and dated 1982. The mints continued to make some copper (bronze or brass, actually) pennies for a year afterwards, but all pennies dated 1983 or later are made of zinc. The only exception is that some proofs and special commemorative issues are still copper. You can tell the difference by dropping a penny on a hard surface. A copper penny will make a ringing sound, while a zinc one makes a dull click.


What is the value of a silver wheat penny dated 1949?

If it appears to be silver silver, it was plated outside the US mint. The U.S. never struck cents in silver. My high school physics class made silver-plated pennies and copper-plated dimes. The alteration makes it worth face value.


How much are 1916 gold pennies worth?

There's no such thing as a gold penny. You have an ordinary cent that was plated with a thin layer of gold. The plating makes it a damaged coin worth only a few cents. It would cost more to recover the few atoms of gold in the plating than you could make by selling the metal.
