The Benjamin Button coin is a popular commemorative fifty pence for coin collectors, though it often isn't worth much.
However, there are several knocking about that could be worth up to £70.

To find it, you'll need to look at the way Benjamin Button is positioned in comparison to the late Queen.
That's because some of the coins contain a rare rotation error which shows Benjamin's head titled further left.
Instead of being parallel and level with the Queen's head, it is positioned more towards the left.
So keep an eye out for this coin as you may be able to get big cash for it.

But sellers could get lucky as one sold for £255 back in 2021 so you may be able to get a bit more.
So get looking through drawers, down sofas and in wallets.
