Commemorative series are sometimes issued (for example, some £5 coins); they are legal tender, but their circulation is more symbolic. testimonial In day to day.
From the pre-decimal system to decimalization
Before 1971, the United Kingdom used the duodecimal system: 1 pound = 20 shillings and 1 shilling = 12 pence (that is, 240 pence per pound). Abbreviations of Latin origin were used: “LSD” for librae, solidi, denariiThe shilling was marked with an “s” (of solidus) and the penny with “d” (of denariusExpressions such as “2/6” meant “two shillings and six pence”; “5/-” indicated five shillings round without pennies.
El Decimal Day (February 15, 1971) changed the system to 100 pence per pound. For a few years, it was referred to as "new pence" (denoted as "p"), until it became simply known as "pence." Previous coins such as the shilling and florin were temporarily equated to 5p and 10p until smaller designs were issued in the 90s and the older coins were exchanged. they withdrew.
Legal tender and acceptance: rules and nuances by region
The concept of “currency of legal tender"In the UK, it's technical: it means that, for the payment of an acknowledged debt, if the debtor offers the exact amount in legal tender or in fiat currencyIt provides a strong defense against a claim for non-payment. This does not imply that a business is obligated to accept any banknote or coin at the counter; in a sale, the parties are free to agree on the method of payment.
En England and WalesBank of England banknotes are legal tender. Scotland and Northern IrelandParadoxically, no banknote is legal tender (not even those from the Bank of England): there, banknotes are legally bills of exchange issued by authorized banks. Even so, they are widely accepted, and in practice people pay as usual. Royal Mint coins, on the other hand, are legal tender throughout the United Kingdom, with bounds by denomination.
In everyday life, it's not uncommon for some businesses in England to refuse Scottish or Northern Irish banknotes due to a lack of understanding, even though they represent pounds sterling. Legally, they can refuse a form of payment if there is no prior debt (for example, if the cashier hasn't paid before handing over the goods). For debts already incurred (such as a restaurant bill), they tend to accept any reasonable form of payment, including cards or checks, although there is no obligation to accept any banknote if it is not legal tender in that place.
Limits on the use of coins as legal tender
The coins have transaction limits (except for some). This table summarizes the maximum amounts that can be used as legal tender in the UK for paying debts in cash:
| Currency | Maximum usable |
|---|---|
| £5 (post-1990 crown) | unlimited |
| £2 | unlimited |
| £1 | unlimited |
| 50p | £10 |
| 25p (pre-1990 crown) | £10 |
| 20p | £10 |
| 10p | £5 |
| 5p | £5 |
| 2p | 20p |
| 1p | 20p |
In practice, these rules apply mainly in courts or debt situations. In retail, what governs is the voluntary acceptance of the payment method; therefore, carrying varied cash Using a card usually simplifies life.
Portraits, addresses and the leap to polymer
British law requires that circulating coins bear the portrait of the reigning monarchTherefore, the pieces have displayed the different official busts of Isabella II over time and, since 2022, the effigy of Charles III.
There is a curious tradition: the head of the new monarch usually faces in the opposite direction to that of his predecessor. predecessorJust as Elizabeth II faced to the right, Charles III faced to the left. There was a historical exception for Edward VIII (whose coins did not circulate) which meant that George V and George VI both faced to the left.
In banknotes, the United Kingdom began the transition to polymer The Bank of England's £5 note in 2016 was followed by the £10 (2017), £20 (2020), and £50 (2021) notes. The £20 and £50 notes were withdrawn from circulation in 2022. Earlier, in 2000, Northern Bank (now Danske Bank) had already issued a commemorative £5 polymer note in Northern Ireland, a pioneering initiative in the UK.
Since 2023-2024, banknotes with the portrait of Charles III have begun to circulate, gradually replacing those of Isabella II as the latter are withdrawn. spentBoth designs coexist, and the queen's remain perfectly valid.
Origins: from the Anglo-Saxon penny to sterling silver
In Anglo-Saxon times, small silver coins called sceattasof about 1,3 g. Around 790, King Offa of Mercia introduced a silver penny of 1,5 g, and 240 of these were equivalent to a “Tower pound”, about 349,9 g. In 1526 the standard changed to the troy pound (373,24 g), standard still used for precious metals.
The term “pound sterling” comes from the alloy of silver and gold. 92,5% (sterling silver) used for coinage. At first, pennies were almost pure silver and wore down; from 1158 onwards, copper was incorporated to give them greater durability. The etymology connects with “pound"as a Roman unit of weight, from which the symbol £ also comes, which in its historical form could be seen as ₤ with two bars.
The Great Debasement (1544–1551) and Gresham's Law
Under Henry VIII, the gold and silver content of coins was drastically reduced to finance wars and Crown expenses. Gold fell from 24 to 20 carats and the silver content reached a minimum of 25%. Many pieces had a surface silver plating over a copper core; as it wore away, the nose of the portrait revealed the copper beneath, earning it the nickname Old Coppernose.
The result was the practical application of the Gresham's Law (“bad money drives out good”): the new, debased coins circulated, while the older, purer ones were hoarded. After Edward VI, under Elizabeth I, the debased coins were withdrawn and melted down (1560), and high standards were re-established. purityregaining confidence.
From the silver standard to the gold standard and the consolidation of the Bank of England
The pound went from a pattern of plata to a de facto gold standard in the 18th century, a process associated with the overvaluation of gold and the reforms promoted by Isaac Newton (1717). In 1816 the gold standard was officially adopted, which sustained the strength of the pound during the financial boom of London as a world center.
The Bank of England, founded in 1694, became a pillar of the monetary system. Despite occasional crises (17th–18th centuries), the pound maintained a reputation for prolonged stability until the wars of the 20th century forced its departure from the gold standard and devaluations later.
20th and 21st centuries: wars, Bretton Woods, devaluations and floating exchange rates
Following the First World War, the United Kingdom accumulated massive debts; deflationary policies led to the depression of 1920–21 and in 1931 The gold standard was abandoned. In 1940, the exchange rate was fixed at 4,03 USD, and under Bretton Woods, the pound suffered significant devaluations. 1949 (at $2,80 USD) and 1967 (at USD 2,40). Exchange controls (e.g., limits on cash when traveling) were also imposed until 1979.
In 1971 Bretton Woods collapsed and the pound went to floatationThere were tensions: in 1976 the government turned to the IMF; in the 80s the pound fluctuated between peaks close to $2 and a low in 1985 of around $1,05. In 1990 the United Kingdom entered the European Exchange Rate Mechanism (ERM) at 2,95 marks; Black Wednesday (1992) forced them out, with rates jumping from 10% to 15% in a failed attempt to sustain the band.
In 2007 the pound reached its highest point against the dollar; 2008 financial crisis It devalued it sharply, bringing it close to 1,02 euros by the end of 2009. In 2009, the Bank of England launched Quantitative Easing (QE) for 75.000 billion pounds, expanded to 375.000 billion pounds in 2012, mainly buying gilts (public debt).
The referendum of Brexit (2016) brought another shock: the pound fell sharply against the euro and the dollar, and since then its exchange rate has responded to a combination of negotiations, domestic politics and global monetary conditions (BoE, ECB, Fed).
