Hi and welcome
If the bottle contained whiskey or some other alcohol that was still drinkable, then it might have some real value. In this case however it is just a sugar syrup so I do not think that really adds much to the overall value.
It is intriguing since it has the labels and foil seal, but there is not a huge amount of visual appeal (for example a label with a large picture or other graphics)
My gut reaction is $10-20, perhaps a bit more. That is my opinion with regard to the bottle collector market.
