What is the dollar value of a set of 1988 encyclopedia brittanicas?

Question

How much do you think I should offer if I were trying to purchase the set?

Answer 1

You might get someone to pay you $10 to haul them away.  Seriously, the internet has practically replaced print reference books and a 20 year old set of encyclopedias has very little value now.  You can see them gathering dust in garage & yard sales all over the country.

Answer 2

seriously? maybe $20. if you really want a set try goodwill and other such stores. people throw out encylopedia sets all the time. getting the online encylopedia is a much better use of money
