I asked him why he thought it was worth that kind of money: "No, I do not mind you asking the question; "What makes me think that anyone would pay £600 for a CD?"The answer to your question is, that CD'S, especially rare ones, sell for a lot more than £600, there is certain CD'S which have sold for £10,000. Some sell from £2000 upwards, and the more rare, the more they will pay for them.I hope I have answered your question, and should you want to know more about valuation, you could always do a google search on rare CD's, and valuations, and you will be surprised at how much certain cd's are. It is just like records, there is one record vinyl that sold recently for £1,000000 that is right, one million pounds, it was the Beatles of course, the white album, but it is not just Beatles albums that fetch big money. There are some that fetch thousands of pounds. It is knowing what to look for.Kind regards,Samiya" Deluded or what………. BTW I've got one of these if anyone wants to make me an offer...
