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.

I think you've misremembered a couple of them (or coins have changed since you learned those facts).

In this link is a table of the current weight of UK coins, including the ratio between each coin and the coin below it: https://chatgpt.com/share/67151004-3fd0-800c-b534-b5933a7305...

2p does weigh double 1p

10p does weigh double 5p

But 50p weighs 1.6x 20p

and £2 weighs 1.37x £1

Huh, you are right. I must have seen the first two pairings (1p/2p and 5p/10p) and extrapolated.
