Macallan 15 year Sherry Oak
Hey there! We are figuring what you have is the 15 year old Sherry Oak which was produced for the US market only and was discontinued about 7 or 8 years ago. This was primarily bought for consumption and not as an investment. Therefore, Macallan does not have any record of any similar bottles coming up for auction to give an indication of resale value. If my assumption is incorrect, it may be a Distillery Exclusive Seasonal Selection. If that is the case, it could be worth £120 - £150.
