I'll post results next week.
Bottomline: Even software that has been abandoned by Microsoft (they don't support this version anymore, but apparently people still want to buy it!) can be a profitable item to list for sale.
The other important lesson is this: don't hold on to your inventory too long. If this had been offered for sale on Ebay several years ago by an owner who didn't need it, then it would have brought in a nice payday, not $20 bucks or so. Move inventory. Have a sale. Clear out non-fiction books and textbooks before they become obsolete.
What do you have hiding on your bookshelves that needs to go now?
