What is the approx. value of a set of 1975 Complete Handyman Encyclopedia's Do-It-Yourself??

Answer 1

I enjoy reading old how to's for a few laughs, however they often contain about 25% still useful information.

I bought a complete set at a garage sale for ten bucks a few years back.  If you are lucky and run across a old how to fan you might get 20.

Cheers

Answer 2

I was at an auction last weekend and my buddy was the only bidder at $10 for something very similar.   In other words, not much.

Answer 3

very little ..with modern techniques most of info is too old to be of use I'm afraid
