The U.K. government is debasing its currency. Literally.
The government is changing the metal composition of its coins to save money. Copper and nickel will be partly replaced in five pence and 10 pence coins with steel.
OK, so nobody out there values the currency they hold by the worth of its constituent metals any more (apart from gold or silver coins).
But the move is suitably symbolic. Both the Bank of England and the U.K. government are aiming to debase the currency through inflation.
