 Collecting 50p coins has become hugely popular over the past few years, with thousands of collectors checking their change to see what special designs they can find. It all started back in 2012 for many of us with the London Olympics when the Royalmen issued 29 different coins each featuring a different sport. Most of these coins have been taken out of circulation now and sit in people's collections but this was just the start and Royalmen have issued many 50p coins each year since then. So which are the rarest 50p coins? We start at the top 10 countdown with three London Olympics coins. At number 10 is the Olympic Shooting 50p which had a mintage of £1,656,500. Next is the Olympic Gold War 50p which had a mintage of £1,615,500. Then at number 8 the Olympic Tennis 50p with a mintage of £1,454,000. Now all of these coins were issued in 2011 in anticipation of the London Games. At number 7 we have Flopsy Bunny. Issued in 2018 this coin had a mintage of £1.4 million. Flopsy Bunny is closely followed by Peter Rabbit. That's the 50p that was issued in 2018 that same year and that also had a mintage of £1.4 million. Number 5 on our list returns us to the Olympics with the Olympic Triathlon 50p with a mintage of £1,151,500. We stick with the Olympics until we get to number 1. So number 4 is the Olympic Judo 50p with a mintage similar to the Olympic Triathlon £1,161,500. The Olympic Football also has that mintage and the 50p is of great interest to lots of people because it shows the offside role explained. Number 2 in our list is the Olympic Wrestling. This had a mintage of £1,129,500. But of course the number 150p in our rare list is the Kew Gardens 50p. This was issued in 2009 and it has a mintage of just £210,000.
