Thanks Damir. I believe that they stopped using tax labels in 1985 so I assume it's from before then. I have another bottle of Crown with a tax label from 1966 but that actually has the date printed on it. I was really hoping someone knew if the numbers on the label corresponded with a date but that doesn't seem to be the case. I doubt there's real value in this and I would prefer to drink it anyway. Just curious more than anything.
