Based on the provided information and established numismatic history, United Kingdom coins intended for general circulation are no longer made of silver. Modern coinage is minted from base metal alloys such as cupro-nickel and nickel-plated steel to ensure durability and manage production costs.
The Royal Mint, as referenced in the first source, does produce and sell a wide variety of silver coins. These products are created for the collector and investor markets and are not intended for everyday transactions. These commemorative and bullion coins, such as the Silver Britannia, are typically struck from high-purity silver and sold at a premium above their face value.
Historically, British coinage contained a significant amount of silver. The title of the second source, "Silver Content of British Coins," alludes to this fact. Prior to 1920, many of the nation's coins were produced from sterling silver, which is an alloy of 92.5% silver. From 1920 until 1946, the silver content in circulating coins was reduced to 50%. In 1947, silver was removed entirely from circulating currency and replaced with cupro-nickel. Therefore, to find silver UK coins, one must look to pre-1947 issues or modern commemorative and bullion pieces.
