I volunteer for an aviation charity and we had a donation of two binders of postal covers from the National Air and Space Museum that are Milestones of Flight covers. We have two binders in like new condition.

Just curious what we should expect to get for them if we list on eBay? Pictures upon request. Thank you for your help!

Sorry to break this news to you but, all but the #1 cover in the National Air and Space Museum Milestones of Flight (MOF) series will go for about a buck apiece. The #1 cover (X-1 supersonic flight 25th anniversary, carried supersonically on an F-104) can command up to $25.

Are any autographed? If so, that can change the whole ballgame here...

I don't believe so.

I figured as much. We'll list for $200 and see what happens! Thanks for your input.
