I have a glass decanter with the words Federal Law forbids sale or re-use of this bottle.

This is a Whyat & Mackay whisky bottle. Is this bottle worth anything?

historic

There is some interest in 20th century bottles but mostly the demand is for bottles that retain their labels (in good condition) and /or their contents.

Yours is attractive and has its stopper...it is a bit better than average.

I could be wrong but I would not expect this to bring much more than $10-20 on ebay...
