Annoyingly, I cant find the link or item number now, but there was one lot of 13 updated 20p's... Buy It Now - £10,000,000. A best offer was made of £7,000,000! Oddly this was accepted within seconds! Obviously there is no way to know if the transaction completed or not (I cant remember the sellers name to check the feedback!) but if that was a genuine offer, I'm properly scared at the level of stupidity!
