The notion of junk silver is not exclusive to the United States. Other countries around the world, particularly throughout Europe, used silver coins for everyday circulation up until the early to mid 20th century when much of the world remained on the gold-standard.
In England, coins minted from 92.5% silver, or sterling silver, were introduced as early as the 12th century by King Henry II. Sterling silver was the norm for most coinage circulating throughout much of the British Empire until 1919.
Pre-1920 British silver coins are often considered “junk silver.” Locally, they are commonly known as “sterling silver” coins, have a silver content of 92.5%. Examples include the British shilling, florin, and sixpence.
Beginning in 1920, the silver content of many British coins was debased and reduced to 50%, or .500 fine silver. This continued until 1946.
