I have an earthenware pot into which I dump my small change: any coins worth less than 50p. (It's like a pot of gold that has suffered hyperinflation.) It was nearly full, so I took the coins to my bank in a very sturdy bag to convert them back to bits. Happily HSBC have a coin counting machine which is free for customers. Here are the results:
|1p (3.56g)||309||£ 3.09||1100.04g|
|2p (7.12g)||163||£ 3.26||1160.56g|
|5p (3.25g)||283||£ 14.15||919.75g|
|10p (6.5g)||294||£ 29.40||1911.00g|
|20p (5.0g)||426||£ 85.20||2130.00g|
The machine also found US$1.91, NZ$0.50, HK$0.50, and €0.02.
