Here are some specific examples of the cost of bread in the early 1900s:
* In New York City, a loaf of bread cost around 5 cents in 1900.
* In Chicago, a loaf of bread cost around 7 cents in 1905.
* In San Francisco, a loaf of bread cost around 10 cents in 1910.
The cost of bread rose significantly during the First World War, due to shortages of wheat and other food staples. By 1918, a loaf of bread cost around 20 cents in New York City.
The cost of bread gradually declined after the war, but it did not return to pre-war levels until the early 1920s.
