What are George V Sixpences made from?

Answer 1

Silver and copper alloy. A sixpence was a silver coin equal in value to six pennies, or pence. Under the British pre-decimal pound/shilling/pence (£sd) system, a pound was valued at 240 pence. One pound was equal to 20 shillings and a shilling was equal to 12 pence.

Up to the reign of George V, all silver coins had a silver content of 92.5% silver and 7.5% copper, called sterling silver, which was the standard set by Henry II.

In 1920, during the reign of George V, the silver content of all British silver coins was reduced to 50%.
