Copper Price History: A 2,000-Year Overview

“Take that copper!” ~ James Cagney, Angels With Dirty Faces,
Dir. Michael Curtiz; Warner Bros, 1938

Right off the bat, copper is a very different metal. Like gold, it’s easy to work with for relatively simple tools and technologies, but unlike gold, copper was (and is) quite common and easy to find. Copper has been mined and used for at least 10,000 years and likely vied with meteoric iron as the metal most used in tools.

Copper’s history as money, is a different story. While gold and silver have almost always been traded as inherent objects of value, the value of copper has often been tied to its utility; a copper knife blade, for example, was worth more than a similar amount of copper (as economic theory would say it should be). Given the low value of copper relative to gold and silver, governments were not always as concerned with making copper (or copper alloys, like bronze) coins available.

Ancient Times
There is evidence predating written history that copper was traded extensively across Europe, the Mideast, North Africa and Central Asia for other goods like shells, food, cloth, wine, slaves and livestock. There is also evidence that the copper trade ultimately drove the exploration for and trade of other metals, such as tin and lead. On its own, copper is quite soft, but in combination with other metals, such as tin, it makes the much stronger, much more useful bronze. Accordingly, bronze weapons, armor, and tools had great value above and beyond their copper content.

Given the nature of the barter economies, it’s hard to characterize the value of copper as money or a trade good. Nevertheless, we know from historical records that 1 deben of copper (90 g) was worth 1 kit (9 g) of silver. We also know that a 58 kg sack of wheat traded for 2 debens. With wages for an unskilled laborer running at approximately 200 kg of grain per month, a day’s wage was worth something in the order of 31 g of copper – a price that works out to approximately $0.25 in today’s copper prices. Other known prices include 5 deben (450 g, or almost 1 pound) for a linen shirt and 140 deben for a cow. As is often the case, manufactured goods cost significantly more in the days before mass production.

It’s also worth noting that copper was more valuable to the Egyptians than it is to us today. In Ancient Egypt, a unit of copper was worth 1/100 that of silver, while today’s ratio is 1:120.

Greece and Rome
Both the Greeks and Romans minted copper/bronze coinage; large hoards have been found buried across Europe. Unfortunately, much of the information we have about trade during that time excludes mention of copper coins. We know that they existed (and in fairly large quantities), but we don’t really know how they were used (or how often). What we do know is that the Greeks valued copper at a ratio of 1:350 with silver.

Middle Ages
Copper/bronze coinage was not minted regularly during the medieval period, as government mints focused on silver and gold coinage. Given that the large majority of the population was too poor to frequently conduct business with gold coins or large amounts of silver, the absence of copper coinage perpetuated trade through barter and credit.

The Byzantine empire was arguably the most active minter of low-value copper coinage, with the bronze folles amounting to 1:288 of the gold nomisma. Soldiers of the Byzantine empire were paid one gold nomisma per year of service. It was arguably the great emphasis on trade in the Byzantine empire that led to the significant production of bronze/copper coinage.

In the late 1500s, England did start minting a copper farthing under King James I, and the German and Italian states periodically produced copper coinage as well. However, copper’s most common use in European coinage was in debasing silver coinage – with Henry VIII famously swapping out as much of two-thirds of the silver content of coins with copper. As Europe moved into the 1700s, bronze coinage became more common, with most major governments producing them.

Modern Era
Copper coinage has been in use for the entire history of the United States – whether in the form of coinage made in Europe and brought over in trade, locally minted colonial coinage, or the eventual half-cent and cent coins minted by the U.S. Mint. Although the modern world has grown accustomed to coins that are always the same size and weight, that has not been the historic norm. Particularly in the early years of U.S. coinage, the idea was that a coin should be worth the weight of the metal. Consequently, the weight of coins shifted with time as copper prices rose or fell relative to the fixed ratio of gold and silver.

Today, copper coinage is an afterthought. The coin most often thought of as copper, the cent, has actually been almost 98% zinc since 1983. At the same time, coins not normally thought of as copper are frequently made with copper clad in other metals; the nickel is 75% copper while the quarters and dimes minted for circulation are nearly 92% copper.

All the same, it is interesting to see how the value of copper has evolved. The large majority of copper is now used in wiring and piping, as well as in circuit boards, power generation and transmission, heating and cooling systems, and telecommunications equipment.

The Bottom Line
From here on, the value of copper is likely to be tied to its utility in applications like wiring, electronics and manufacturing. Cheaper alternatives, such as plastic, have increasingly been replacing copper in finished goods and construction, but copper is still the preferred metal for a variety of electrical applications, including electrodes, turbines, generators and so on. It is also still a major input in renewable energy systems.

The world has all but entirely moved away from the idea that the metal content of a coin must have something to do with the value of the coin. Barring a complete re-thinking of fiat money and specie, that is unlikely to change. In fact, even copper coinage, historically the cheapest to produce and largely used only by the least well-do to in the economy, is now seen as antiquated and arguably too expensive.

About admin

Please allow me to introduce myself; I am Jeffrey Bennett, President of Kettle Moraine, Ltd., the parent of Sierra Madre Precious Metals. I have been married for 52 years with two children and four grand-children, a veteran of Viet Nam, student of history (both American and film), and was host for fifteen years of Perspectives on America on the alternative airwaves, covering such subjects as, health and wellness, news, political satire, education and editorial commentary on current events through the teaching of history, and Protecting Your Wealth. In early 2018, I took a several month hiatus to complete some family business but returned to airwaves April 17, 2018). At the age of ten, I sat in a bank-vault in the Citizens Bank of Mukwanago, Wisconsin with my grandfather going through bags of old American Peace dollars, hand-selecting each coin as dated rolls of 20 coins were carefully put together and rolled. Learning of the history of these beautiful pieces of Americana, I asked my grand-father, "Why are we doing this?" to which he replied, "Because someday they are going to do the same thing with the silver in our money that, that (S.O.B.) Roosevelt did with gold in 1933." It took only six-years for his prediction to come to pass at the hands of a disciple of Roosevelt's... and what will a Federal Reserve 'dollar' purchase today - and what will that old 90% Silver Peace Dollar purchase? Although at the age of ten, there was little understanding of the meaning of it all, over the next half-century I became well-versed on the subject matter. During this summer of my education, I began to purchase silver coins as a collector and some small, international gold coins two years later - not an easy feat in the shadow of the Roosevelt confiscatory policies of 1933. Although those policies remained in effect until the mid-1970's, it was not until 1991 that I found that one could make a living providing precious metals and collectible, historic numismatic coins to a willing and concerned clientele. It was also during that year, that I began a relationship with one of the first Trust companies to give the public access to gold and silver as part of an Individual Retirement Account (IRA) - and Kettle Moraine, Ltd., founded in 1995, but have ceased providing service due the the intense change-over of the provider. In November 2011, after a 15 month broadcast on another network, I returned to the airwaves with my then revamped program, Life, Liberty & All That Jazz, and for over a quarter-century, I have been proud to serve the family of listeners of my numerous broadcast programs for physically-held precious metals for investors and collectors alike. On March 23, 2020 I launched my brand new - appropriately named program, The Edge of Darkness on the Republic Broadcasting Network, and thus continue to  remain available to our long time clients and their families. Ah yes - find out what "inter-generational" wealth provision has done for our clients over the past three decades. Don't buy the sizzle of that steak until you understand the cost! In other words, don't buy the bull being dispensed by the 'rare coin' pitchmen until you understand the full story. We, at Sierra Madre Precious Metals, will be proud to serve your needs.
