Old Rip Van Winkle Bay Colony Bicentennial decanter

Whiskey decanter ‘1975’ Any bottle collectors (or one who takes interest in things like this) out there who can possibly give some general info. for this specific decanter? I’m not sure of the history there. There is no whiskey left, so seal is broken and that alone decreases the value immensely. Aside from monetary value, I think it’s a pretty cool piece!
