Johnnie Walker Gold N Blue Label N Liqueur
It is highly unlikely your 2 bottle presentation of JW Blue and Gold is worth much. Probably just the retail price. Unless a miniature is EXTREMELY rare, collectors are not fond of minis that have evaporated. You have two very common miniatures in the JW Box. As for the Signatory Glenugie, if in mint condition with no evaporation, and in the original tube it was packaged in, you can expect ~US$35.00 - US$40.00. I am familiar with your Glenugie and it is considered a TRUE MINIATURE as are your JW's. A TRUE MINIATURE is a mini that FAIRLY represents the full size bottle packaging; note I said FAIRLY, as minis cannot exactly depict the full size bottle. After having collected miniatures for ~15 years, mini collectors will go to the ends-of-the-earth to acquire a much sought after mini; mini collectors possess a passion greater than that of full bottle collectors. Being from England, your best bet is to contact the MINI BOTTLE CLUB and talk with a member.
