2 Pounds - Charles III Tower of London

The Tower of London's connection to coinage is literal: the Royal Mint operated within its walls from 1279 under Edward I until 1812, making it one of the longest continuously occupied mint sites in English history. The Isle of Man Treasury has issued under its own authority since the Coinage Act 1970, which separated Manx coinage from the UK system and gave the island latitude to produce commemorative bimetallics that the Royal Mint itself would not typically strike for domestic circulation.
