Dewar's Fine Old Scotch Whiskey 1 Gallon Bottle. Full. Age? Selling price?

[jordanm]

Hello,

I have a 1 gallon bottle of Dewar's Fine Old Scotch Whiskey. I am not sure of the date but from what i can read of the back of the front label it has written 21170 ZI. Can someone help me to determine the age of the bottle? And if anyone has any idea how much to sell this for please let me know. Thanks.

jordanm - can you post a photo of your bottle? Need to know what type of closure is being used and there's a coat of arms at the top of the label- is there an indication of which Monarch? (does it mention Queen Elizabeth or By Appointment to His Majesty the King?) These are just some rough guides to give an idea. I know that later bottles of Dewar's had a date on the backside of the label as you're seeing - but I'm not able to figure out those specific numbers. Is this by chance a new bottle?
