What is the gold standard, and what is fiat money?

A gold standard is a rule that ties a unit of currency to a fixed quantity of gold, so that paper can be exchanged for metal at a stated price. Fiat money has no such promise attached. Its value rests on public confidence, a central bank, and the state that issues it.

The difference is easiest to see in a price. Before 1933 an American dollar was a claim on gold at a fixed price of $20.67 per ounce of pure gold, a figure the Federal Reserve still cites when describing the era (Federal Reserve History, Roosevelt's Gold Program). That number was the whole system in miniature. Fix the price, promise to honour it, and every note in circulation becomes a warehouse ticket. Break the promise, and the same piece of paper has to earn its keep some other way.

Collectors tend to meet this distinction backwards, through the notes. A 1928 United States note and a 1963 note of the same denomination look like cousins, yet one carries a redemption clause and the other does not. The story of that missing sentence is the story on this page. For the longer arc that leads into it, start with our history of paper money.

Why were early banknotes receipts rather than money?

Because that is literally what they were. A goldsmith or a bank took in metal, issued a written claim against it, and the claim circulated because it was lighter than coin and easier to carry. The wording on early notes was not decoration. It was the contract.

The Bank of England was founded in 1694 to act as banker to the government (Bank of England, our history), and its notes still carry a promise to pay the bearer on demand (Bank of England, banknotes). For a long stretch that promise was suspended. When France declared war in 1797 a run on gold cut the Bank's reserves from about £16 million to about £2 million, and Prime Minister William Pitt ordered the Bank to stop paying notes in gold. The Restriction Period ran to 1821, and the Bank's own account notes what filled the gap: small denomination notes multiplied, and so did forgery.

American notes were built the same way. The Demand Notes authorised by Congress in 1861 to finance the Civil War were redeemable in gold or silver on demand at seven designated banks, and the Treasury issued gold certificates from 1865 and silver certificates from 1878, each backed by metal held in Treasury vaults (US Currency Education Program; Bureau of Engraving and Printing). Those two families of certificate are the most direct collectible survivors of the receipt era, and we cover them separately in our gold certificates guide and silver certificates guide.

Why did countries leave the gold standard?

Because a fixed gold price and a domestic emergency cannot both be satisfied at once. Under a gold standard a government defending its parity has to let money, credit and prices contract when gold flows out. In a war or a depression that is the opposite of what a treasury wants to do.

Britain found the limit first. Confidence in sterling collapsed in 1931, the Bank of England lost much of its reserves in a run on the currency, and in September 1931 the United Kingdom suspended the gold standard (Bank of England). The United States followed within eighteen months for a similar reason: banks were failing, depositors were converting deposits into gold, and every ounce that left the system tightened the screw further.

It is worth separating this from the collapses catalogued elsewhere in this library. Leaving gold is a policy decision made under pressure. Hyperinflation is a currency losing its meaning in public, and the two are not the same event, as our explainer on hyperinflation versus inflation sets out. Britain in 1931 and the United States in 1933 left gold and kept their currencies. Germany in 1923 kept a currency that had already stopped working.

When did each major currency leave gold?

There is no single exit date, because most currencies left gold more than once and in more than one sense. The table below tracks the moments that mattered and, in the last column, what the change did to the words printed on the note.

Sources for the table: Bank of England, Federal Reserve History on the Gold Reserve Act of 1934, US Currency Education Program, Federal Reserve History on the end of gold convertibility and Federal Reserve History on the Smithsonian Agreement.

What happened to American gold in 1933 and 1934?

Three separate actions, often compressed into one by retellings. An executive order in April 1933 called gold in. A congressional resolution in June 1933 cancelled gold clauses in contracts. An act of Congress in January 1934 transferred the metal to the Treasury and set a new official price.

Executive Order 6102, signed 5 April 1933, required gold coin, gold bullion and gold certificates to be delivered by 1 May 1933. President Roosevelt issued a proclamation on 20 April that formally suspended the gold standard, and on 5 June a congressional resolution abrogated gold clauses in all contracts, public and private (Federal Reserve History). The Gold Reserve Act followed on 30 January 1934, transferring ownership of all monetary gold in the United States to the Treasury and ending the public's right to convert dollars into gold. The new official price of $35 per ounce took effect the next day, 31 January 1934, under Proclamation 2072 (Federal Reserve History). The Federal Reserve puts the closing date plainly: Federal Reserve notes have not been redeemable in gold since 30 January 1934 (Board of Governors of the Federal Reserve System).

The restriction on private gold holding in the United States was eventually repealed. Public Law 93-373, signed on 14 August 1974, permitted United States citizens to purchase, hold, sell or otherwise deal with gold, and took effect on 31 December 1974 (Public Law 93-373, US Government Publishing Office). Gold certificates never came back as circulating money. They came back as paper history.

What was Bretton Woods, and what ended it in 1971?

Bretton Woods was the postwar monetary order agreed in July 1944 at the Mount Washington Hotel in Bretton Woods, New Hampshire, where delegates from 44 nations built a system in which the dollar was fixed to gold at $35 an ounce and other currencies were fixed but adjustable against the dollar within a one percent band.

The conference created the International Monetary Fund and the International Bank for Reconstruction and Development, now part of the World Bank Group. The IMF came into formal existence in December 1945 when its first 29 member countries signed the Articles of Agreement, and the system became fully operational in 1958 when currencies became convertible (Federal Reserve History, Creation of the Bretton Woods System).

The design had a weakness built in. Only the dollar was tied to metal, and the United States had to supply the world with dollars while keeping enough gold to honour them. By 1971 the arithmetic no longer worked. On 15 August 1971 President Nixon announced that foreign governments could no longer exchange their dollars for gold, closing the window that had held the system together (Federal Reserve History).

The wind-down took eighteen months. The Smithsonian Agreement of December 1971 devalued the dollar against gold by roughly 8.5 percent to $38 an ounce, a net average devaluation of about 10.7 percent against the other key currencies. On 12 February 1973 the United States devalued by a further 10 percent to $42 an ounce, and within a month nearly all major currencies were floating (Federal Reserve History, The Smithsonian Agreement). Every banknote issued anywhere since then has been fiat money.

What changed on the banknote itself?

The obligation line. That is the sentence near the top or bottom of the face that states what the issuer owes the holder, and on American notes it was rewritten twice in 35 years. Reading it is the fastest way to date a note's relationship to metal.

The three American obligations

Series 1928 Federal Reserve notes carry a redemption promise in gold. Series 1934 notes replace it with redemption in lawful money, the phrase that still appears in the United States Code, which provides that Federal Reserve notes shall be redeemed in lawful money on demand at the Treasury or at any Federal Reserve bank (12 U.S.C. 411, Cornell Law School). Series 1963 notes drop redemption language altogether and state only that the note is legal tender for all debts, public and private, which follows the 1963 congressional prohibition on redeeming currency for gold recorded by the US Currency Education Program.

The British case

British notes went the other way: the promise stayed and the payment stopped. A Bank of England note still promises to pay the bearer on demand, wording inherited from an era when that meant gold coin. Since the 1930s the promise has been honoured in other Bank of England notes, which is exactly how a receipt becomes fiat money without a single word of engraving changing.

The silver postscript

Silver ran a decade behind gold. The Federal Reserve records that its notes have not been redeemable in silver since the 1960s (Federal Reserve Board), and United States notes, the old red seal legal tender notes, stopped being issued in 1971 because they no longer served a function that Federal Reserve notes did not already cover (US Currency Education Program). For the certificates themselves, see our silver certificates guide.

Which gold era notes do collectors buy?

The pieces that show the promise in print. Gold certificates with their orange backs, blue seal silver certificates, Series 1928 Federal Reserve notes with the gold redemption clause, and the Series 1934 notes that replaced it are the core of a collection built around this story, and they can be assembled in almost any budget because condition drives the price.

A good beginner set is a comparison set. Put a Series 1928 note beside a Series 1934 note and a Series 1963 note of the same denomination, and you have the whole transition on one album page in three sentences of engraving. Nothing else in the hobby explains a monetary revolution that economically. Add a silver certificate and a gold certificate and the receipt era is covered too.

Buy on grade, because grade is what separates a common note from a scarce one within the same series. Our banknote grading guide walks the ladder from Uncirculated down through AU, XF, VF, F, VG and Good, and what determines banknote value explains why two notes with the same catalogue number can sit far apart in price. Values move with series, signature combination, star note status and condition, so treat any single figure you see quoted as a snapshot rather than a rule.
