My dad gave me these, he was going to throw them out, someone gave them to him years ago and he doesn’t smoke and neither do I ... how can I tell if the cigars are still in the box (I’d be shocked if they weren’t since nobody smokes at all in the family) ... but the boxes feel light (maybe they always do?) ... I’d like to sell them, but I don’t even know if someone would buy them, so I don’t want to open the boxes ... are these cheap? Nice ones? Middle of the road? Where can I find out what (if anything) these are worth? Do they go stale? Because these are probably 30 years old or more, if I had to guess ...
