Last weekend, I spent an hour or so counting and sorting the coins in my change jar. Obviously what I should have done was arrange the coins in little stacks and made myself a chess set like this one:
Of course, I wouldn’t have had the banknotes to make the board, but I’m sure I could have improvised something or other. Or maybe not.
 I throw all my loose change into a jar at the end of each day. I count it up and pay it into the bank on a “when I get round to it” basis.
 The current jar is a tall transparent plastic one that once contained Quality Street, if my generally addled memory serves me
