I'm not a collector but it has my interest of the history dated with 2 seals 100 proof first date 1916 unopened ?????

I always am looking for different things I'm really not a collector of liquor it belong to my grandfather I don't know alot about history about prohibition but I think this was made during that time period and the distillery was suppose to be closed.There are two seperate dates on the seals one being 1916 and the second being 1923.I thought maybe someone could tell me a little more about it or if it is something to hold on to!
