Luhrman’s experience highlights a growing conundrum for the Mint and for U.S. taxpayers. Primarily because zinc, too, has soared in value, producing a penny now costs about 1.7 cents. Since the Mint currently manufactures more than seven billion pennies a year and “sells” them to the Federal Reserve at their face value, the Treasury incurs an annual penny deficit of about fifty million dollars—a condition known in the coin world as “negative seigniorage.” The fact that the Mint loses money on penny production annoys some people, because one-cent coins no longer have much economic utility. More than a few people, upon finding pennies in their pockets at the end of the day, simply throw them away, and many don’t bother to pick them up anymore when they see them lying on the ground. (Breaking stride to pick up a penny, if it takes more than 6.15 seconds, pays less than the federal minimum wage.)
Various people have proposed various remedies, one of which is to get rid of pennies altogether. This is a step that many countries have taken with their least valuable coins—among them the United States, which stopped making half-cents in 1857, when a half-cent, by almost any measure, had significantly more purchasing power than a dime does today. There are problems, though. One is that many people are quite attached to one-cent coins. Another is that some people fear that merchants in a penny-free economy, when making change on cash purchases, might be more inclined to round up than to round down, thus penalizing consumers. A third is that eliminating pennies would increase our reliance on nickels, which now cost almost ten cents to manufacture and so generate even more negative seigniorage, per coin, than pennies do. What is to be done?
America’s assortment of circulating pocket change is anything but immutable. Colonial-era settlers initially had no coins (or bills) of their own. They therefore depended heavily on barter, and conducted cash transactions with British coppers and other foreign coins, especially Spanish reals. (The “dollars” mentioned in Article I of the Constitution were actually eight-real coins, also known as pieces of eight.) British silver coins were scarce in America because Britain, which had little domestic access to precious metals and hoped its colonists would soon get busy shipping treasure in the opposite direction, forbade their export. In 1702, the alchemy-obsessed master of the British Royal Mint, Isaac Newton, melted down and minutely analyzed the coins of a number of countries to determine their exact content. The results of Newton’s assay were used, among other things, to set the bewildering, constantly shifting exchange rates that were a part of daily commercial life in England and America in the early eighteenth century.
