I am helping a friend to sell his autographed magazine collection. We do not know what the value of these are and would greatly appreciate your input. The ones above were signed by, Tommy Ivo, Shirley Muldowney, Don Garlits and George Barris.
I would look at ebay's completed listings for an idea. Not saying it's the best but it might give you somewhere to start. Those of us that have tried to sell the same mags haven't had great success. Best wishes for your task.
Between the two they pretty well nailed it. The value is the autograph on the magazine cover that shows the person who autographed it and most likely the best place to list it is on Ebay with a reserve that he is good with. You have to find that hand full of people who just flat have to have it and get in a bidding war in the process. Presentation means a lot though and if he happens to have a photo of any one of them signing the magazine that included in the add probably raises the value a bit.
