Value of Encyclopedia Set?

1950s sets tend to not have a ton of value. They have a book from that set on eBay for $15 but no recent completed auctions to see what people have actually paid for these books.

I would say that a set from the 50's has no value. You will be lucky to give it away. Some people make sculptures; some make lamps out of this type of book. It is not old enough to be collectible or an antique. The information is outdated. See if you can find someone who you can give it to for craft projects.
