Where did all the silver coins go?

By JP Kroning – April 9, 2019

In times past, small denomination coins were made of silver. The U.S. quarter dollar, for instance, once contained 90% silver, which meant that each quarter had 5.6 grams of precious metals. But in 1965 the U.S. Mint stopped issuing coins with silver in them. These days, a quarter is mostly copper with some nickel.

In the UK, coins contained 92.5% silver up until 1920, and after that were 50% silver. But nowadays, there isn’t a trace of precious metals to be found in any of the circulation coins minted by the Royal Mint.

Why did coins go from being composed mostly of silver to having no silver at all? The answer is simple: technological progress. People discovered that the monetary system worked more efficiently once the denominations formerly represented by silver coins were replaced by coins that contained base metals like nickel and copper. In this post I’ll walk through how “silverless” coins improved the monetary system. But first we have to head back 200 years to the early 1800s.

The Great 1816 Recoinage

At the outset of this post I mentioned several famous 20th century reductions in the silver content of coins. But these were preceded by a series of prior reductions. One of the very first curtailments in silver’s role in coins occurred in Britain in the early 1800s. In 1816, with the passage of the Coinage Act, Parliament declared that the Royal Mint would henceforth reduce the weight – and thus the silver content – of Britain’s silver coinage. Shillings, crowns, and half-crowns would all be affected.

This was a big deal! For centuries, the Royal Mint had guaranteed that any new shilling that it minted would contain ~5.6 grams of silver. From 1817 on, this long tradition would come to an end. The silver content of a freshly-minted shilling would be reduced by 6% to ~5.2 grams.

Even though British coins now contained 0.33 grams less silver, Parliament declared that they were to have the same value as before. So a new shilling – though lighter than the old one – would still be worth 1/20th of a gold pound, just as it had been in decades past. For the average British coin user, the passage of the Coinage Act didn’t change anything. Their lighter shillings could buy just as much food, beer, and clothing as before.

Tokens vs full-bodied coins

Parliament’s proclamation didn’t just reduce the silver content of Britain’s coinage. It changed the very nature of Britain’s coins. Silver coins issued by the Mint had always been full-bodied. This meant that at the time it was issued, a shilling contained about a shilling’s worth of silver in it. Put differently, the market value of a new shilling was equal to the market value of the metals of which it was composed. But after 1816, England’s silver coins would no longer be full-bodied. They would function as tokens.

A token coin is worth more than the market value of the metal of which it is made of. For example, with one post-1816 shilling – which contained 5.2 grams of silver – Brits could purchase around 5.5 grams of silver. (This is at the 1817 market price of just over 5 shillings/ounce of standard silver, or 0.16 shillings per gram). In other words, a shilling’s worth of silver was worth more than the silver in the shilling.

How could a shilling be worth more than its silver content? The issuer – the Royal Mint – promised to limit the supply. If necessary, the government would repurchase or redeem tokens at their face value with gold coins or banknotes. Lastly, legal tender laws forced debtors to accept these coins at their face value, not their metal value. This set of guarantees ensured that tokens passed at a premium to their bullion value.

Bimetallism and coin shortages

The reduction in the silver content of the coinage and the adoption of token format was a brilliant way to fix a very particular problem that was then plaguing Britain: shortages of small change. Coin shortages were a fairly typical under a bimetallic standard. This was the monetary system that Britain had officially been on for several centuries.

Under bimetallism the pound unit of account – the £ – was jointly defined by the monetary authorities as either a fixed amount of gold or silver coins. This had the effect of establishing an exchange rate between gold and silver. But the system broke down whenever the authority’s chosen exchange rate for the two metals diverged from the market’s exchange rate. When this happened, one of the two metals would be undervalued relative to the other. In Britain’s case, it had been undervaluing silver since the beginning of the 1700s.

Thanks to the undervaluation of silver, silver coins like shillings were more valuable if they were melted down, exported, and sold at their true value as bullion. There had thus been almost no silver coins in circulation in Britain through most of the 1700s and early 1800s. But Brits were in desperate need of small value coins like pennies and shillings to purchase goods and pay salaries. Shortages of change meant that trade became difficult to carry out.

Here is how one letter writer in 1771

the problem:

“The scarcity of Change has been severely felt by People in Trade for upwards of these Ten years past, and this Scarcity increases daily; and base designing People avail themselves of it, by getting Credit for trifling Sums, which they never intend to pay.”

Stop the melting

The 1816 recoinage removed the incentive to melt down coins for their bullion value. By instituting a 6% decrease in the silver content of the shilling, half crown, and crown, Parliament ensured that the market value of silver in each of these coins was significantly below the coin’s market value. Henceforth, it would make little sense for a Brit to melt down a shilling in order to use it as bullion – said shilling would always be worth far more in coin format. This brought an immediate end to coin shortages and the resulting chills these shortages imposed on trade.

The only way that Britain would re-encounter coin shortages is if the market price of silver, which was then at 5 shillings per ounce (or 0.16 shillings per gram), spiked to around 6 shillings per ounce and stayed there. At that point the shilling would cease to be a token. The value of the 5.2 grams of silver in a post-1816 shilling would be worth more than the shilling itself, and it would once again be melted down. But this did not become a problem: silver prices would stay low for many decades.
