They are as rare as the auction suggests. This one has a higher serial number than any others I have encountered (usually only three digits) but that doesn't necessarily mean it isn't right. It is hard to tell from internet photos but certainly looks good. If it is a fake it is the best I have seen so far, and if it is legitimate its current bid is about 1/3 of its collector value.
