My grandfather just passed away and I found this box in a cupboard. I'm wondering if I have a gem or should I use it as decor for my bar? It is an unopened bottle of NIKKA Gold & Gold 43% with a Samuri Armour & Helmet for a gold & gold whiskey bottle. I'm guessing on the date. I couldn't find a replica when I googled it. Does anyone know what it might be worth?
