Can't be quite sure untill we can see the bottle itself (Might be 1950-70).
From the weight description, you have a 1/2 size bottle...not so highly collectable, but depending on condition of the exterior & the fill-level of the
contents, it may be worth $50-$100.
If you can email me photos of the Top, Bottom & Front, I can have your
bottle dated for you, and get you a valuation.
