How can I find the value of old magazines?

There is a book called - Old Magazines: Identification & Value Guide by Richard E. Clear You can probalby find it on ebay or amazon but I would recommend that you just see if your local library has it. Or, try a reputable antique dealer. A lot will try to lowball you on the price if you try to sell it to them, so it's better to say, that you're not selling but curious to know how much their worth. Also, if you go to your local Barnes & Noble or Borders store and check in the collectibles dept., they should have a price guide that would list prices for magazines. I'm not sure if they'll have that one but you can try. Good luck & Hope that helps.
