Can someone help me date this bottle of kahlua?

I found a set of three bottles of Kahlua in these nice tins. I can’t find a date on the bottle or tin of when this is from. It was in a box of other alcohol, bottles of wine from the late 1970s.

I’d like to know when this is from, as well as if it is very old, is it still safe to drink. It’s still sealed and was stored in a cool, dry place.
