People are advertising undated 20p's on one side only, these are normal 20p's and people are paying 20-30 quid for something that is worth 20p.!! i can't get my head round it - stop being scammed, the only ones that are worth anything are the ones with no date front and back, with part of the lion crest on it. Not an old one from 1999 that just so happens not to have the date on one side.!! Wake up people.!! Check VERY CAREFULLY that you are not being scammed, these people are ready to run with your money, you have been warned.
