If you're a whisky drinker, and especially if you like smoky whiskies (particularly from Islay), I don't see how you can go wrong opening up this bottle. What a great treat to drink and share with friends.
On the other hand, if you're not a whisky drinker, either test the waters with something more "entry level" and see if you might want to open this some day, or consider gifting it to a whisky-loving friend/relative.
You'd score some big points by gifting this one.
If none of that appeals to you, then yeah...you can certainly make a few bucks off of it.
