[placeebo effect]

people who are pulling these things out and are trying to sell them have probably done a quick search on ebay and took the highest price they saw and are thinking "I have gold. Its better than the one listed for $xxx. So I will charge more." and start out at the high price being the neophite that they are, and causing the huge price surge. Personally I say not to worry. Soon the price will come crashing down like in the housing market. Price correction will happen when they get the hint that the Cub they have isn't wort nearly as much as the think it is.
