Twenty pounds (British coin)

"Twenty pounds" is a special type of coin from Great Britain. It's called a "twenty pounds" coin because it's worth twenty pounds - that's like having twenty of the one pound coins you might be used to.

But this isn't just any old coin - it's actually really big and really fancy! It's made out of special metals and has a super special design on it that makes it look really cool.

People don't use it very often, though, because it's worth so much money. They might keep it as a special souvenir or give it away as a special gift to someone really important.

So, basically, it's like having a really fancy toy that's worth a lot of money and people only use it or give it to special people.
