Since the distillery no longer exists and in addition since you have a single malt produced from Glenlochy (most production went into blends), there should be some value here. Unfortunately Whisky.com does not offer valuations at this time and neither does Glenlochy's parent company - Diageo. However, I'll see if I can dig up some info for you. Also, if you're in the US - try contacting Park Avenue Liquors (212-685-2442) or the Brandy Library (212-226-5545) - both do valuations. If you're in Europe - try McTears.com or Bonhams.com Be sure to post your findings here
