With the outbreak of World War I in 1914 the government issued Treasury Notes to £1 and 10s which replaced gold coins in circulation and the public were requested not to demand gold. On 1920 August 07th Gold Sovereigns ceased to be legal tender for use in Ceylon by Proclamation of King George V and the sovereign became Bullion. The Gold Standard Act of 1925 made currency notes nolonger exchangeable for gold.
Note that King George~V, St George Sovereigns were minted with Mint mark on the representation of ground on reverse.

The coins that were Struck during the war years became part of the gold reserve of the Bank of England. Part of the considerable debt to USA was paid in Gold, and since USA cannot hold any gold coins, any of the coins recieved would have been melted into ingots. In 1929 and 1930 over £91 Million from Bank Reserve was also melted. This made the 1916, 1917 and 1925 Sovereigns from London Mint rare. However the Royal Mint restruck 886K 1925 George V Sovereigns between 1949 to 1952 during the reign of George VI, which made them common again probably to the dismay of numismatists of that time.
