Will U.S. Mint Change Coin Compositions?

By 1857, the value of copper had increased so much, particularly from the effects of inflation, that the U.S. Mint ended the production of half cents after that year. That year it also changed the size and composition of the one cents to be smaller coins.

In 1982, the U.S. Mint changed the metal composition of the cent to reduce the costs of striking these coins.

It may be time once again for the Mint to alter the composition of current coins issued for circulation or to discontinue production of one or more denominations altogether.

As currently manufactured, here are the specifications of U.S. circulating coin metal content:

Cent: gross weight 2.5 grams with 97.5% zinc, 2.5% copper

Nickel: gross weight 5.0 grams with 75% copper, 25% nickel

Dime: gross weight 2.27 grams with 75% copper, 25% nickel

Quarter: gross weight 5.67 grams with 75% copper, 25% nickel

Half Dollar: gross weight 11.34 grams with 75% copper, 25% nickel

On Tuesday, March 8, the price of nickel more than doubled in trading on the London Metal Exchange before this market suspended trading. At the close of trading on the London Metal Exchange that day, the “official” price of nickel was $48,201 per metric ton, but trading was suspended at $100,000.

Using the official prices for the close of trading on the London Metal Exchange on March 8, here are the value of the raw material metals in each of the above coins:

Cent: 0.948 cents

Nickel: 9.84 cents

Dime: 4.467 cents

Quarter: 11.157 cents

Half Dollar: 22.315 cents

If you use a value of $100,000 per metric ton for nickel, metal values for the nickel through half dollar increase to 16.314 cents, 7.406 cents, 18.500 cents and 37.000 cents, respectively.

Raw material costs are only one component of producing coins. There are also labor costs and overhead. In addition, the Mint strives to realize a seigniorage gain that is turned over to the U.S. Treasury.

Obviously, with the total production costs of the cent and nickel in excess of the face value of these coins, the Mint has a strong incentive to either change the metal composition of these coins or to end their production altogether.

There are precedents for ending production of small denomination coins. In May 2012, the Royal Canadian Mint ended production of the Canadian cent. In February 2013, merchants were no longer required to accept these coins in payment and were directed to round cash transactions to the nearest 5 cents. Banks were then directed to return all 1-cent coins they had received back to the government for destruction.

Other countries that have retired smaller denomination coins in recent decades are:

Australia: 1 cent and 2 cents in 1992

Brazil: 1 centavo in 2005

Finland: has never issued 1 cent or 2 cents coins since the introduction of the euro denomination in 2002

Israel: 1 agora in 1991 and 5 agorot in 2008

Netherlands: stopped issuing 1 cent and 2 cents in 2004

New Zealand: 1 cent and 2 cents in 1989 and 5 cents in 2006

Norway: 10 ore and 25 ore in 1991

Sweden: 10 ore and 25 ore in 1992

Switzerland: 1 centime in 2006, with the 2 centimes having lost legal tender status in 1978

United Kingdom: 1/2 penny in 1984

With the significant increases in consumer prices over the past year, this may be a prime opportunity for the U.S. Mint to retire 1-cent coins and either significantly alter the metal composition of or retire the nickel. Even the metal content for dimes, quarters and half dollars may need alteration at this time.
