I have recently come across 519 issues dating from the current back to 1952 national geographic magazines. I am looking to sell them on eBay and currently there is only one issue missing. I am wondering how much to start bidding at. I have looked on eBay and for something similar but not in as good of condition or as complete and starting in 1967 the asking bid was almost $130.00. I'm just looking for a little input into the selling on eBay. I have purchased from eBay but not sold yet. TIA
