Gold vs the Pound in Your Pocket

Put two coins on a table. The first is a gold sovereign struck in 1925. The second is the pound coin in your pocket today. Both say one pound. The sovereign weighs 7.98 grams at 22 carat and contains 0.2354 troy ounces of fine gold, and it circulated as a one pound coin because that is precisely what a pound was defined to be. At the sterling gold price on the morning this was written, 23 August 2026, the metal in that sovereign is worth about 794 pounds. The modern coin is worth one pound. Same name, same face value, one century apart. This is the arithmetic of what happened in between.

What a pound used to be

On 21 September 1717, Sir Isaac Newton, Master of the Royal Mint, reported to the Lords Commissioners of the Treasury on the flight of silver coin to India. In doing so he devalued the guinea and set a price: three pounds seventeen shillings and tenpence halfpenny per standard ounce of gold, and four pounds four shillings and elevenpence halfpenny per ounce of fine gold, about 4 pounds 25 pence in decimal money. The World Gold Council's note on the document records that, apart from the Napoleonic suspension, "this price persisted until the early 20th century."

It outlived the man who set it, and Napoleon, and Victoria. Britain suspended it for the Great War, restored it at the old parity in 1925, and then, on 20 September 1931, the Treasury announced that it had "become necessary to suspend for the time being the operation of Subsection (2) of Section 1 of the Gold Standard Act of 1925". More than 200 million pounds had been withdrawn from London since mid July. The counter closed. It never reopened.

The terms get rewritten

From that day the pound was a promise, and the terms of a promise can be altered by whoever wrote them. They were, three times in one working lifetime.

In September 1949 Sir Stafford Cripps devalued sterling from 4.03 dollars to 2.80, a cut of just over thirty per cent. On Saturday 18 November 1967 James Callaghan cut it again, from 2.80 dollars to 2.40, a devaluation of 14 per cent. The following evening Harold Wilson went on television to say that "the pound here in Britain, in your pocket or purse or in your bank" was worth no less than before. The House of Commons Library's own fiftieth anniversary retrospective treats that broadcast as the defining false comfort of the era: devaluation raised import prices, and inflation followed. Then, on 15 August 1971, the last thread was cut for every currency at once, which is a story we have already told.

The scoreboard

These are not our numbers. The Office for National Statistics publishes a Retail Prices Index long run series running back to 1800, indexed to January 1974. On that series 1914 stands at 9.8 and July 2026 at 1,653.3. So one pound of 1914 needs about 169 pounds today to buy the same basket, and 99.4 per cent of its purchasing power is gone. Take only the years since 1971, where the index reads 80.0: prices have multiplied about twenty times, an average of roughly five and a half per cent a year.

Now gold over the same fifty five years. In 1971 the official price was 35 dollars an ounce and sterling was pegged at 2.40 dollars, so an ounce was 14 pounds 58 pence. As this was written it stood at about 3,374 pounds, or 108 pounds a gram. That is a multiple of about 231, against a multiple of about 20 for prices. Measured from Newton's parity instead, gold has multiplied about 794 times, which is the same number as the melt value of that 1925 sovereign, and not by coincidence: the sovereign simply was a pound of gold.

Priced in real things

Index points are bloodless, so price the pound in objects. The official UK House Price Index, run by HM Land Registry and calculated by the ONS, puts the average United Kingdom home at about 4,180 pounds across 1971 and at 272,188 pounds in June 2026. In gold that is roughly 287 ounces then and about 81 ounces now.

Wages tell the same story from the other end. In October 1970, Hansard records, the average weekly earnings of full time manual men were 28 pounds and 5 pence, close to two ounces of gold every week. In June 2026 average weekly total pay across the whole economy was 755 pounds, about 0.22 of an ounce. Those are different jobs in a different Britain, so call it simply a working week: it buys about an eighth of the gold it did. Priced in pounds everything rose. Priced in gold most things fell. Priced in work, the gold itself got dearer too, which is worth holding on to.

The honest chapter

Gold's terms are silence. It pays no interest, no dividend, and promises nothing, and it can fall for twenty years at a stretch. It did exactly that between 1980 and the end of the century, so convincingly that in 1999 the Treasury began selling. About 395 tonnes went at seventeen auctions between July 1999 and March 2002, raising around 3.5 billion dollars, or 1.9 billion pounds. That works out at roughly 150 pounds an ounce, and the same 12.7 million ounces would fetch something near 43 billion pounds today. At that price the average house of the day cost well over five hundred ounces of gold, far more than in 1971 and many times today's figure, which is the clearest possible proof that this ratio swings violently, and that today's reading says as much about gold at record highs as it does about the pound.

The National Audit Office examined the programme and found the sequential auctions "a very transparent and fair sales mechanism", with prices in line with the London Gold Fix, and its head concluded that "in designing and implementing the gold sales programme so far the Treasury has done well". The lesson is not that officials were fools. It is that twenty years of honest evidence about gold can still be wrong about the century.

Why the pound thins

The mechanism is very old. The Royal Mint's own account of the Great Debasement records that between 1544 and 1551 Henry VIII replaced precious metal with cheaper copper, the thin silver wearing away first at the king's nose, which earned him the name Old Coppernose, and public trust in the coinage fell with it.

The modern method needs no shears and no furnace, and it is worth being fairer here than this subject usually is. Moderate inflation is declared policy, argued openly, with real benefits claimed for it. The Chancellor's remit to the Bank of England states plainly that "the operational target for monetary policy is an inflation rate of 2 per cent" and that it "applies at all times". Nothing is hidden. But run the arithmetic on the target itself: at exactly two per cent, prices double in almost precisely thirty five years. On target, by design, in public, the pound loses half its purchasing power once a generation. Nobody devalues by decree any more. They do not need to.

What it comes to

The pound in your pocket is a promise, and the terms of that promise have been rewritten in every generation since 1914: in 1931, in 1949, in 1967, in 1971, and quietly, at two per cent, ever since. The ounce has no terms, because nobody wrote it. It also makes no promises: no interest, no dividend, no floor, and it has punished plenty of individual decades. Which of them you hold, and in what measure, is yours to decide. We have only done the arithmetic. Meanwhile the institutions that issue the promises have spent four years buying the metal, and if you hold gold you no longer want, you can sell it to us at a published price you can check against the same figures used here.
