Bell's Scotch Whisky
 

I have a bottle of Bell's Old Scotch Whisky noted on the bottom of the bottle as "EXTRA SPECIAL." It is at least 25 years old. It is a 40 oz (38.4 US oz or 1.14 litre) bottle. Just below the neck is a label that says "Afore ye go." Does anyone have any idea what it might be worth, if anything?
