I Have Some Old Mad Comic Books From The Early/mid Fifties. Where Can I Get A Price Guide On These? You Can Get Back To Me.

There is a price guide at this link: www.collectmad.com. I'm not sure if this guide covers Mad comics from the 1950s but you may be able to find something on there to help you.

You could also try this this website: www.newkadia.com, which has some information on early Mad comics and some prices which may give you an idea of ow much they are worth.

Hope this helps.
