We went from a monetary system that only your grandparents could figure out to base 100.

Pounds, shillings, and pence

The coinage used in Victorian Britain had been much the same for three hundred years and was based on a system which had existed for more than a millennium. It lasted until 1971 when the currency was finally decimalised and the pound was divided into 100 smaller units. Similar changes were made to the currency in Ireland and several Commonwealth countries which still used Britain's ancient coinage system.


In Britain the pound Sterling was (and is) the central unit of money. Prior to decimalization the pound was divided into twenty shillings and each shilling was divided into twelve pennies or pence. Although those divisions may seem odd, in fact having a pound divided into 240 equal parts does mean it can be exactly divided into halves, thirds, quarters, fifths, sixths, eighths, tenths, twelfths, fifteenths, sixteenths, twentieths, twenty-fourths, thirtieths, fortieths, forty-eightieths, sixtieths, eightieths, and one-hundred-and-twentieths. A decimal system allows precise division only into halves, quarters, fifths, tenths, twentieths, twenty-fifths, and fiftieths.
