What was 1 pound worth 1919?

It uses inflation indexes for major countries. These are also called Consumer Price Index (CPI) and represent Cost of Living.

Several currencies and indexes are available: Consumer Price Index (CPI) for US dollar (United States) published by US Federal Bureau of Labor since 1913, French Insee index (for euro, franc and old franc), Canada (canadian dollar), Switzerland (Swiss Franc), Italy (euro and italian lira), Germany (euro and german mark), United Kingdom of Great Britain and Northern Ireland (sterling pound), Japan (yen), Argentina (argentine peso), Russia (ruble), Australia (australian dollar), New-Zealand (new-zealand dollar), Europe, etc...

Notice: The information contained in the Archival Currency Converter 1916–1940 is accurate as at 1 March 2019. Changes in circumstances after this time may impact on the accuracy of the information. David Challis gives no assurances for any information contained in the Archival currency conversion application after that time and makes no commitment to update it.

Notes relating to the data contained in the Archival Currency Converter 1916–1940:
The data used in the Archival Currency Converter 1916–1940 was sourced from the archival United States of America Federal Reserve Bank report titled, ‘Section 11: Currency’ in the Banking and Monetary Statistics, 1914 – 1941. This report can be found at: FRASER®, Federal Reserve Archives, Federal Reserve Bank of Saint Louis.

The data points used in the Archival currency converter were calculated using the monthly exchange rates between the US dollar and various other currencies as recorded in the above US Federal Reserve Bank report between 1916 and 1940. The original pages from this report for the United States dollar foreign exchange rate against the Argentinian peso, Australian pound, Brazilian milreis, French franc, German mark, Japanese yen and British pound are shown below.

These exchange rates were used to calculate the arbitrage free exchange rate between the French franc and the Argentinian peso, Australian pound, German mark, Brazilian milreis, Japanese yen and British pound. For example, using the month of January 1916:

• The US dollar rate against the French franc was 17.1045 US cents per franc or 5.8464 francs per US dollar.
• The US dollar rate against the British pound was 476.80 US cents per pound or 4.768 US dollars per pound.
• Therefore the arbitrage free exchange rate (known as a ‘cross rate’) between the French franc and the British pound was 5.8464 * 4.768 = 27.8757 francs per British pound.

Note that the physical exchange of gold under the International Gold Standard did, on occasions, give rise to arbitrage margins occurring between various currencies. These margins are not reflected in the numerical data which are representative of 'official' exchange rates only.

It is also important to note that each of the currency reports used from the Federal Reserve Bank 'Section 11: Currency' report have individual notes regarding the quotations that were used when gathering the data between 1916 and 1940. The currencies used in the Archival Currency Converter were not subject to structural changes during the period between 1916 and 1940 except the German mark which presents a number of structural complications. The Goldmark was replaced by the Papermark on 10 April 1917 which in turn was replaced by the Riechsmark on 28 October 1924. As a result of the incidence of hyperinflation in Germany the exchange rate for the Papermark was dramatically devalued in the period between July 1923 and October 1924 meaning that the recorded exchange rates could not be sensibly used in the Archival Currency Converter. In addition, no data was recorded by US Federal Reserve for the Papermark in the period between May 1917 and August 1919 presumably due to hostilities in the First World War.

There are quite a few websites that show you approximate costs, i.e. "the cost of living" would tell you that you could get an average house in London for 300 pounds.

If you want to look into smaller items, check here or here:

• Bread would cost 12.5 pence (d) = 1 shilling and 2 farthings. So for one pound, you could buy about 20 loaves of bread (unless my math is off)
• 1 ton of coal was 1 pound 35 pence
• Sugar was about 0.07 pound per kg
• Milk was about 0.07 pound per pint
• A weekly grocery was about 0.51 pound

So for example, the 200 pounds in the original post would be enough for a 2/3 of a house in London, even if by the rough inflation calculation it is barely 11,440 current pounds. Just to compare, the average price in London in the cheapest suburb was in 2019 around 290,000 pounds (over 690,000 if you look at the whole city, including super expensive areas). On the other hand, currently, bread in UK costs by average around 1 modern pound, so if we stick to the 57.2:1 conversion rate, you could buy almost 3 times as much bread for the same value.

BTW, let me quote Terry Pratchett here, explaining the nuances of the old currency system:

Two farthings = One Ha'penny. Two ha'pennies = One Penny. Three pennies = A Thrupenny Bit. Two Thrupences = A Sixpence. Two Sixpences = One Shilling, or Bob. Two Bob = A Florin. One Florin and one Sixpence = Half a Crown. Four Half Crowns = Ten Bob Note. Two Ten Bob Notes = One Pound (or 240 pennies). One Pound and One Shilling = One Guinea.

The British resisted decimalized currency for a long time because they thought it was too complicated."
