The coins are part of the "Tales of the Earth' series and have been released in partnership with the United Kingdom's Natural History Museum.
The first coin of this series features the apex predator Tyrannosaurus Rex, a.k.a., T-rex. This is the first time the mighty Tyrannosaurus Rex has been depicted on a UK fifty pence pieces. It is the only carnivore in this series.
This collection is three-part. It has two more coins, one of which will display the Stegosaurus, a herbivorous, four-legged, armoured dinosaur from the Late Jurassic period.
The third coin features Diplodocus, a gigantic herbivorous dinosaur known for its long neck and legs.
Prices of the coin start at £11 ($13.90), and the most expensive join in this collection is the Gold Proof Coin carrying the price tag of £1,220 ($1541.51). The coins are available for purchase on the Royal Mint website.
Paleo-artist Robert Nicholls is behind the design of these coins. The designs were made in collaboration with the Natural History Museum's Professor Paul Barrett.
The coin designs offer accurate reconstructions of the dinosaurs and their habitats, based on current understanding. To bring the huge creatures to life, some coins will even feature colours.
