I too am more than a little sceptical! I believe one of the two confirmed, known specimens sold for in the region of £20K so if true, this would be bargain of the millennium! Go on then - did anyone here get it, and more importantly, is it the real McCoy and can we see a picture?! Given Goulbourn have, I believe, taken over Croydon Coin Auctions and are now running them from Chester, surely they would know what a genuine third example could command and indeed would be a real feather in cap for their auction business. I would only be convinced in the veracity of this with a decent picture...!
Or has it been doctored, perhaps?
