A bottle of 50-year-old Glenfiddich is among the leading lots of Bonhams' whisky sale in Edinburgh on June 18.
Bottled in 1991 and numbered "5", it comes with its own wooden case and estimate of £12,000-£14,000 ($20,000-24,000).
That valuation is shared by The Macallan Millennium, bottled in 1999 following a 50 year ageing process. It arrives at auction in a Caithness glass decanter.
A cask of 25-year-old The Macallan sold for $102,500 in Hong Kong last month.
