As the title any one know how much this is worth ....it is mine and not a copy, comes with setup floppies as well.......I want to sell an old computer but think the op system is probably worth more than the computer

Depends on how much someone's willing to pay for it. In my experience, that isn't a lot due to the high availability of dodgy copies...

If you're selling it with an old computer most people will expect it (or even XP!) on there and also not expect it to cost them any extra.
