Websites that provide values of collectible UK coins include CoinQuest.com, CoinsBG.com and Coins-Of-The-UK.co.uk. The values given are an indication only. The value of very rare coins can only be tested at auction.
The most valuable British coins include early large size guineas, a number of proof sets, massive gold coins and sovereigns that pre-date Queen Victoria. Silver florins and crowns, trade tokens and early shillings are less valuable, although can still be worth hundreds of U.S. dollars. Modern coins are generally less collectible with the exception of the Maundy money introduced in 1953 during the first year of Queen Elizabeth II's reign.
