if you are interested, I have a copy of Martin Green's valuation book based on McTears Whisky Auctions and he lists the Glen Moray Vintage 1966 as being worth around 150 GBP as of 2001.
Personally, I think it should now be worth more than this, for two reasons:
1. I would have expected the price to increase in the last 5 years.
2. The McTears quotations are based upon prices achived in 'real-life' McTears auctions. These prices do tend to be lower than many other (internet-based) auction sites, mainly due to the extra charges which accompany them. I speak of Buyers' premiums and VAT which a buyer has to pay on top of the winning bid price. These usually ensure that buyers win items for a lower 'sale price'.
I have record of the 1959, 40 y/o being sold on Ebay.de in 2004 for €703.
I hope this helps,
