Not only do they have amazing pictures of dinosaurs on them but they also are the first-ever to use augmented reality (AR).
Royal Mint, which makes most of the the UK's coins, used the latest colour printing techniques to vividly show the megalosaurus, iguanodon and hylaeosaurus on the coins.
After receiving the coin, collectors can use AR to scan the packaging to unearth facts, clips and images about the prehistoric beasts.
