Hi, I am very much a rookie when it comes to scotch. I have a bottle of Ambassador Deluxe Scotch, 4/5 quart, 86 proof. The tax label has these numbers: CIN-I-67 and 465759718. It is aged 8 years, and we have had it for about 18 years. Never opened. I am wondering about the quality and possibly the value.

Thanks to anyone who can help.
