Hello, I bought The Kings Mountain Fortress complete with an original box for around $75.00, how much value does the box add to the set? Thanks!

Hi, welcome to the site. If the box is in good condition and the set has instructions and all the pieces, I can see the set possibly being worth double what you paid for it. Collectors like boxes and if the box is in excellent condition, the set could be worth quite a bit more than an non-boxed used set. Most of these old sets do not have boxes and many are lucky to have instructions. Even if it's used, a complete set with box, on a rare and old set like this, is very valuable.
