The Royal Mint has shared a festive riddle on social media that has left users scratching their heads.
Getting into the Christmas spirit, the coinage manufacturer tweeted: "You've heard of elf on the shelf. Now get ready for..." The message was accompanied by an image of a UK one pence coin featuring the portrait of King Charles III.
The iconic Elf on the Shelf has become a Christmas staple in homes across the world. The festive tradition refers to the well loved children's book of the same title which tells a rhyming story of how Santa figures out who's naughty or nice with help from one of his elfin workers.
