Think about it. The government is basically saying: “Please, for the love of tea, stop using these old bits of cotton paper.” But they can’t just take your money.
So they create this zombie currency. It’s legal, but not really. It works, but only if you find a nice bank teller. It’s a game of monetary hide-and-seek.
Some people hoard old notes for fun. They think they’ll be worth more later. Spoiler: They usually aren’t. They’re just damp paper.
The Real Gems
If you have a rare serial number on an old paper note, it might be worth something to collectors. A “low” number like AA01 000001 can fetch hundreds of pounds.
When do old £20 notes expire and are they still legal tender?
But a regular, worn-out paper twenty? It’s worth exactly twenty pounds. Nothing more, nothing less. The magic is in the promise, not the paper.
That promise still exists. The Bank of England has never defaulted on a note. They are the most reliable borrower in history. They take their paper very seriously.
