They make a shield!

So I've only been at this for a month and I've already used up one of my emergency blips!

You may have worked this out ages ago, but I only recently realised that the seemingly random designs on the back of all that shrapnel in my bag actually make a clever puzzle - the answer being on the back of the pound coin.

There are no numerals, no Britannia on the 50p, no Welsh emblem - but I still think it's jolly clever.

(Which is more than I can say for me - I think I got the 5p upside down!)
