British coin values are also proportional to weight, within the groupings that can be put together in the little coin bags.

2p weighs twice as much as 1p.

10p weighs twice as much as 5p.

50p weighs 2.5x as much as 20p.

£2 weighs twice as much as £1.

20p is particularly convenient, at exactly 5g.

Same weight as 1 sheet of 80gsm A4 paper!

(A4 sheet area is 1/16 of a square metre)
