Well there in lies the problem; one expert says it was authentic and one expert says it wasn't. By that standard the fact that there is a difference of opinion is enough for me to say that actual value is indeterminate. So really what is being advocated is that the seller shops for an opinion that will support his ideal not the truth of the matter which, since its altered, the intrinsic value of the components. If the seller thinks different then throw in out on the general market with all the avenues to sell it. Put it on Ebay, Reverb, etc., determine when he needs it sold by then highest offer accepted at that time and its true value is now know. Dealers really don't want to mess with this stuff these days because there is so much that doesn't have issues coming back on the market. I know one dealer that doesn't even take consignments in anymore and just buys them out right because availability of good pieces are so plentiful right now. As been said many times on this forum and in many posts the vintage market is shrinking, fewer new buyers are stepping in at the the listed price points and sellers are looking to retire and cash out. Buyers who want the vintage specs can get that need met with these great reissues and at a significantly lower price.
