The very early Apple II's are worth quite a bit of money but you have to know what you are looking for. If you are buying them for scrap pay scrap prices and do a little look over before you strip them. Too many people think because some computer is old it is worth money, most of it is broken junk. Tons of Apple II's were purchased by schools and somebody hung onto them for too long after the school dumped them.
