I need to dispose of my late husbands collection. besides his personal collection I have boxes of gems pre 1980. I am trying to organize it. Will sell all or part. 1900 on, early years not complete. Not sure where to start.
Start with Mel's excellent article on selling National Geographics:
I'm sure many of us would like to know what you have from 1900 to 1910. Condition is important. To me, the condition of the spine matters a great deal since that is what you see when the issue is on the shelf.
