My parents are about to give away a bottle of Dewar's White Label Scotch Whisky, and while I know that it is an inexpensive whisky, I am curious to figure out how old is it and what the value may be. I can't find a date, I found a similar but not exact photo of a label that said about the 1960s. There is a number "382012630" on the seal on the top and the other side of the seal says "schenley import company New York, NY"
Any clues? Am I looking at the right place? Thanks
