I have about 26 years of National Geographics from 1980 to 2016. They are in the National Geographic 6 month binders. There are about 5 missing months. I was tempted to sell these on ebay but I have questions about the quality of the magazines. They are not in mint condition but I think they are better than good. There are a few scuffed spines and a few spines with some dark spots, but the insides are all good. What would you consider the condition of these magazines to be in and what is the possibility of being able to sell them in mass? What would postage run for about 300 NG's with the binders? Thank you for any information.
