The original Gibson guitars hold their value good - some older ones or special artist models may even increase in value. Copies do never (apart from a few extreme exceptions of quality guitars built in Japan) increase in value. They only lose value. If you're lucky and this turns out to be a good playing guitar, and if you get it in good working order with new strings and a good set-up, maybe, just maybe, you could get $100-150. You will have to realize that you get good, new guitars these days for the same price...
