A 64-year-old Glenfiddich Rare Collection 1937 whisky could set a new auction world record when it comes to Christie's in June.
Distilled in 1937 and bottled in 2001, it is just one of 61 specimens produced, making it the rarest Glenfiddich ever released.
Bottle 42, which comes in its original wooden case with key, has an estimate of £50,000-70,000 ahead of the Fine and Rare Wines Including Rare Spirits sale in London on June 7.
It is unknown how many bottles remain of the collection. At the time of release it was the world's oldest single malt whisky.
The current world record for a whisky bottle at auction stands at $94,000 (£59,350), set by a Glenfiddich Janet Sheed Roberts Reserve in March, a rise of 26.6% for the record in three months.
Chris Munro, the head of wine at Christie's London, commented: "The already global collecting base within the whisky market continues to grow, with a great deal of crossover from our established wine buyers, and I've no doubt this bottle will invite a flurry of interest from collectors both old and new."
Recent research by valuation experts Whisky Highland reveals that the top 10 performing whiskies grew in value by more than 400% between 2008 and 2011.
The sale will also feature a Glenfiddich Private Reserve 1955, valued at £8,000-12,000, and a Macallan Select Reserve 52 year old, estimated at £5,000-6,000.
