Hi, I have a £2 coin savings pot. I opened it today and saw I have quite a few rare £2 coins, I was just wondering if anyone would be able to help me out and see if any of them are actually worth anything. I have checked all and narrowed down the ones with minting errors like upside down writing and missing/faint dots around the Queen, I’m just not sure where to go from there?
