Anna, In making this decision, you have to understand a little of the history of this error coin. When they were first discovered some months ago, examples were going on eBay for initially £250 or so. As more and more were found, the law of supply and demand took over and prices started to fall, until around a week ago you could get one for £25, which is probably the going rate. Then all of a sudden the Times 'broke the story' and suddenly the world and his wife goes mad trying to find these error coins and prices on eBay rocket to, as you say, £5800 - there is one on there at present for £8000 on a 'buy it now' basis. However, for a coin to be worth this kind of money it usually has to be extremely rare. Take the 1933 penny, for instance, of which there are about 6 examples. These go for huge money if they are ever available, but precisely because they are so rare. The question you need to ask is whether this coin is truly rare and the simple answer is no, as there are currently some 250+ examples on eBay at the moment. Also, there has been a steady stream of these on eBay for months now, and the Royal Mint seems to think that there are 200,000 examples out there. If you consider that the 1913 third farthing had a mintage of 288,000 only, yet you can buy one in very nice condition for £50 or less then you will see that this error coin whilst scarce and interesting is not rare. So what do you conclude from this? Firstly, the current bubble will subside when people start to realise that there are not fortunes to be made from this coin, just a modest profit, if you are lucky enough to find one. Secondly, to get any kind of premium price, you need to get in quick whilst the bubble is still expanding. Thirdly, forget the sort of four figure sums seen on eBay. If you look at the £5800 coin you will see that the anonymous bidders who took it up to £5000 or so, all have virtually no feedback and are, therefore, in all probability fake bids to try and push the price up or 'fix' the market in peoples minds. I doubt very much whether they were genuine bids and I also doubt whether the winning price will be paid. More likely the seller will claim a refund of fees from eBay from a non-paying bidder. Hello DaveG38 Thanks to you too for taking the time to respond to my post. Looks like we will be putting the coin on ebay and we will be happy with what we get! Hopefully there will be someone daft enough to pay over the going rate for this coin. If not what ever we get will be more that '20p'! I have found info given by yourself and Rob who also responded very helpful - I will not be buying a safe to keep it locked up in for a few years! Thanks again guys Anna
