The rarest 10p, 50p and £2 coins have been revealed - and you may want to keep your eyes peeled for one specific coin that has jumped 23 spots since its release in October.
One has even sold for £250 online, so it’s well worth checking your change to see if you’re the lucky owner of any of these rare coins.
These findings are based on the latest Scarcity Index published by website Change Checker in November.
