Nostalgia time as 50 years ago (from Feb 15th 1971), that the British currency went decimal.
Those of certain age will/may remember it (fairly?) well.
Here are a few links

The £ (which had 240 pennies in it) could be divided to equally pay 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 60, 80, 120 and 240 (that’s 19 times).
Go back in time a little more to when there were half pennies (pronounced ha’penny) there were 480 in a £.
Another step back and there were farthings ( a ‘fourthing’, half a ha’penny) so now we have 960 to the £.
And yet another step back in time (pre 1870), there was the half-farthing, 1920 of these little blighters to the £.
Today’s decimal £ can only be divided by 1, 2, 4, 5, 10, 20, 25 and 50 (which is only 8 times)
