Johnnie Walker Black age
Hi, this is a late 1970s bottling - not 1960s. This can be ascertained from the label stating 75.7cl 70 proof 26 2/3 FL OZs. In all likelihood the rear label "77" part refers to 1977 and then is followed by a batch number - so that the distillery can recall bottles if required using this identification number. As to value - Johnnie Walker is the world's largest selling scotch and these bottles are therefore not "rare" even though it is from the 1970s.
