Hi, I have lots of NG ephemera. Letters, brochures, book mark, coin, plate etc. I have been collecting for about 20 years. It's time to start selling. I was wondering where I could get information on values. There isn't much of this kind of stuff on ebay.

Donna, As I long time collector of all things NGS and as one that has bought and sold many ephemeral items over the years, I appreciate your situation. The best luck that I have had in selling items and realizing what I considered was a fair value was when I sold the items to an up and coming collector with adequate resources. I am not aware of any price lists that can give you values of your items. It is my experience and opinion that the value of any National Geographic item is basically what you can get for it on any given day. I have found some unique items on Ebay over the years, but Ebay has never been a good source for determining values. It all comes down to what someone is willing to pay. The nice thing about this forum is the fact that you can offer items without having to pay the costs involved with selling items on Ebay or other auction sites. On the other hand, if you get two or more people bidding on an item, the price will usually go up. So there you go. I know I haven't really answered your question, but I just don't think it can be definitively answered. Good luck!

to donna plourde,

do you have for sale any of the plastic coated sales versions of map supplements that were issued with the magazine. they were rolled or folded. i am especially looking for the 17 historical map making of america series that were issued in the 1980's and the 6 making of canada supplements in the 1990's.
