A Jacobite drinking glass presented by Bonnie Prince Charlie to his secretary, Sir John Hay, is valued at £7,000-9,000 ($11,237-14,447).
It will provide one of the highlights of Bonhams' November 12 sale in London.
The glasses were presented to aristocratic supporters of the prince, known to history as the Young Pretender.
A note on the base of the glass relates its origin: "One of a pair, stated to have been the gift of Prince Charles to his treasurer and secretary JOHN HAY, who served throughout the 1745 campaign, was major-domo of the Household & went with Charles to Rome in 1766, created a baronet & left Charles' service in 1768 Dec. 8th."
Another Jacobite drinking glass sold for £43,000 ($68,500) in 2012.
