1p Die Stamped Into A 2p Coin

Looks like a hammer job - the reverse lettering is the clue.

Looks to me like the Penny is the wrong way round. Look at the number 1. The flat area on the other side of the 2p makes it look like it has been placed into a press, the 1p placed on top of it, and the press closed. My guess is that someone did this at their workplace to see what would happen. This might explain why the 2p is no longer exactly round. All good clean fun!

I agree - the coin was damaged post mint.

The other (and perhaps far more common) way of making such a coin is to have a large and heavy but wobbly piece of furniture, so you put a couple of coins under one of the furniture legs to stop the wobbling. Then you leave it there for a couple of decades before removing the coins. It's the same effect: two normal coins get squeezed together, and the design from one coin gets stamped into the other.

There is, presumably, somewhere out there a matching 1p coin that's been squashed flat on the obverse and has a faint impression of a large queen-face stamped into the reverse.

The out of round appearance and the backwards lettering is a give away of it being damaged. PMD. Classic Vise Job. Not an error. https://www.error-ref.com/squeeze-j...-garage-job/
