The estimates are all over the place. Some low but could be mistaken for "come and get me" estimates (most Beatles, Marley) and others ludicrously low (e.g. Hendrix). I think I would avoid the auction altogether. The Cilla may be OK but I think everything in the auction is tainted by the things that aren't real.
well the bad news is that autographs sold, - but the good news is that most punters must have sussed that the items were fake as most of them sold for ridiculously low prices
