Sorry, valuing second hand glasses is not my forte. They used to be sold by Farlows in Pall Mall over 20 years ago, and they jusat might, for reasons of sentimentality ,depending on condition & wear and Tear, be interested in buying them back!
contact the buyer peter.sant@farlows.co.uk website. That quantity is really a top up for an existing collector, and phots would be needed.
I trust they have not been in a dishwasher, with resulting bloom?
Good story for Andy McC on tejh Antiques Road show and he is onsocial media, so let him know, perhaps.....
