I'm not a flag collector but I was hoping some of you experienced & knowledgeable folks might be willing to give me insight. I've got this flag that was given to me as thanks by my Congressman and I'm trying to massively downsize my possessions so I am trying to get rid of it - This flag is different than most that have flown over the U.S. Capitol as it was specifically a historic commemorative occasion celebrating the September 18, 1993 bicentennial laying of the US Capitol's cornerstone laying by Pres. George Washington. It comes with a certificate and a commemorative foldout poster. I have zero idea what this is worth - I've put it up on eBay but I don't know how far off base I may be with the asking price of $100 or what I should accept if someone gives a best offer since I have no idea what may be fair. Can anyone give me advice?
