LONDON — Queen Elizabeth II is the only woman now pictured on currency in England and Wales. That is about to change.

The Bank of England on Tuesday unveiled the final design for a new 10 pound bank note bearing the likeness of the novelist Jane Austen, timed to mark the 200th anniversary of her death.

The polymer bill, worth about $13 at current exchange rates, joins its cousin, the £5 note featuring former Prime Minister Winston Churchill that was introduced last year.

(Unlike the United States, there are no bank notes issued in England and Wales for less than a “fiver.” Instead, the Royal Mint produces £1 and £2 coins. A new 12-sided £1 coin was introduced in March.)

The new bills, set to enter circulation in September, are made from a thin plastic material designed to be more hard-wearing than traditional paper notes, able to withstand a washing machine cycle. Last year, the governor of the bank of England, Mark J. Carney, famously dipped one of the new £5 notes in a curry to show its durability.

The roots of the pound date back to well before the founding of the Bank of England, or of even the Kingdom of England itself.

The First Pound

Historians generally attribute the beginnings of the pound to silver pennies used by the Anglo-Saxons in the 8th century. About 240 of those coins were supposed to be equivalent to a pound of silver, though the weight varied.

The roots of the £ symbol representing the currency trace back to the Latin word libra, meaning a pound of money.

The first pound coin, however, was only introduced seven centuries later by Henry VIII in 1489, and it bore his likeness.

At the time, there probably was no practical need for a currency of such high value. But it served to bolster the image of the Tudor dynasty across Europe, according to the Royal Mint.

The Beginnings of Paper Money

The first paper notes emerged in Europe in the 16th century: Goldsmiths began accepting deposits of gold coins, and would issue receipts redeemable for cash.

The Bank of England was established in 1694 to help finance William III’s war with France. The central bank soon began issuing handwritten deposit receipts for specific amounts in pounds, shillings and pence, all signed by the chief cashier. The notes promised then — as they do now — to pay the bearer the sum of the note on demand.

The first £10 note, an ancestor to the Jane Austen bill, came in 1759 as the country grappled with a shortage of gold resulting from the Seven Years War.

It was not until 1833, however, that notes issued by the Bank of England became legal tender.

Modern Pounds

The Bank of England and other countries have had to continually update their currency, as counterfeiters have become more sophisticated, by adding holograms, watermarks and using special paper to print notes.

The biggest shift in recent years has involved switching from a special cotton-based paper to a polymer bill.

Polymer allows the bank to add more sophisticated security features on notes, and means that the bills should last two-and-a-half times as long as their old paper counterparts.

The £5 bill includes a see-through security window featuring an image of the queen that changes color when the bill is tilted, a hologram that changes from “five” to “pounds” when moved, and the numeral 5 when the bill is placed under ultraviolet light.

Similar features will be found in the new £10 note.

The introduction of the new £5 notes last year was not without controversy.

The bills used a tallow, or hard, fatty substance usually made from rendered meat, as part of their base. That angered vegetarians and vegans in Britain.

That tallow was also used in the new £10 notes already printed.

The bank has decided not to withdraw the bills in which the tallow was used. But it is considering using palm oil as the base for its upcoming new £20 note, which will feature the British painter J.M.W. Turner and is to enter circulation by 2020, as well as any reprints of its £5 and £10 bills.

Women on the Currency

There was an angry reaction when the Bank of England announced that Mr. Churchill would be featured on the new £5 note, replacing the prison reformer Elizabeth Fry and leaving England and Wales without a woman on its currency. (Banks in Scotland and Northern Ireland print their own pound notes, with several featuring women.)

Shortly after becoming the Bank of England governor in 2013, Mr. Carney announced that Ms. Austen would replace Charles Darwin on the £10 note.

In the United States, the Treasury announced last year that Harriet Tubman would be the new face of the $20 bill. Leaders of the suffrage movement will also be added to the $10 bill and a former first lady, Eleanor Roosevelt, will appear on the $5 bill, along with the African-American singer Marian Anderson and the civil rights leader the Rev. Dr. Martin Luther King Jr.

Sacagawea, a Shoshone guide who assisted the Lewis and Clark expedition, the suffrage leader Susan B. Anthony and Helen Keller, the activist for the disabled, have all appeared on American coins. Martha Washington, the former first lady, has previously featured on a $1 silver certificate.
