Glenfiddich 'Bonnie Prince Charlie' Single Malt Scotch Whisky
Finally found the right person at Glenfiddich to ask - here ya go - directly from the Glenfiddich Distillery:
"This ceramic was done for a number of years in the late seventies and early eighties and was part of the Bonnie Prince Charlie & Mary Queen of Scots series. They were sold in the UK for £17.45 each and are currently worth around £75.00." This is around $120 at current exchange rate.
