Are old versions of software collectable?

Steve has been cleaning out an old storage unit and found a ton of old boxes of vintage software. Will they be worth anything? Leo says that probably not. It may be worth it to the computer history museum in Boston or the Smithsonian. But they may already have copies. Those were so common that all of that old software is probably more common than he'd think. On the other hand, a few minutes on eBay will tell him if it's worth anything.
