How much is my whisky worth?

A 1970 bottle of glen grant 1970 bottled in 2009, rather than 2003 is currently priced at €98 on an auction website WhiskyAuction.com togther with a couple of others at €200 with days to go. Ebay sold some 24 and 25 year old for around £50.00 and thewhiskeyexchange.com has a number priced retail from about £100.00 up. So I think you should be able to get around a hundred for it.
