I was more continuing the binary digit theme, but at the same time it is a more common note. £50 notes are generally for doing crimes, buying cars or making shopkeepers stare exasperatedly at you.

I think it's a joke, "£10" could look like a binary number.

Alternatively, there are a lot more £10 notes in circulation, and the previous £10 note had Charles Darwin.

It would at least get seem more. Last time I saw a £50 note was I think around 1998.

All these comments about how rare £50 notes are really make me want one.

If you're in the UK, just go to your bank and ask to withdraw £50. Job done.

If you're somewhere else, go to your local money exchange place with the equivalent of £50. I almost guarantee they will have some.

I'll sell you one for £55

I think the OP was making a point about the £10 being binary: a 1 and a 0
