Here are the ones experts reckon could be worth the most in years to come. To help, ChangeChecker has created a scarcity index that tracks all 66 circulating 50p coins based on their worth. If you can get your hands on one of the original Peter Rabbit coins from 2016 - you're looking at a lump sum worth up to £500.Īccording to the coin experts at ChangeChecker, the lower the mintage number, the more valuable the coin can be - and right now there are five 50p editions in circulation that are classed as 'scarce' and 61 more that are classed as potentially valuable. One of the rarest of them all - the Kew Gardens design – is worth up to £400 on auction websites (in mint condition) but it's not the only one collectors are willing to pay a lot more than just face value for. It's been 52-years since the 50p first entered circulation, and since its launch in 1969, we've seen dozens of variations of the seven-sided coin enter our pockets. We've all heard about the £5 notes with valuable serial numbers and the rare round pounds, but what about the hidden treasure 50p coins out there?
