Every year the Royal Mint release new coins, and in the last couple of years we've seen some fantastic designs, including Peter Pan, Gruffalo, Professor Stephen Hawking, Peter Rabbit, and the infamous Sir Arthur Conan Doyle character Sherlock Holmes!
Change Checker have now updated their Scarcity Index to reveal which designs are worth more than others, and the latest results show the Kew Gardens 50p remains on top of the list. The rest of the Top Five coins also remaining unchanged - Football, Triathlon, Wrestling and Judo.
Having a quick search on eBay for 50p coins reveals a number of designs currently with Buy It Now prices of £40,000 are more.
Collectively, the Olympic 50p coins are the most sought after with the Top 17 places of the scarcity index dominated by their designs. In fact, the Kew Gardens one is the only non-Olympic design.
The biggest change according to Change Checker is the Olympic Canoeing design and the Battle of Hastings, both of which have moved up six places!
Although the Scarcity Index doesn't actually reveal how much the coins are worth, it does reveal how sought after the different designs are, but if you think you have an unusual coin you can use their six point guide to see how much it could be worth.
