Rare American History Items for sale

[amhistory55]

What is the most unusal, rarest thing dealing with American History that you have seen for sale on E bay? I have seen an autograph collection from all the presidents before, and currently there is a shell casing from the shootings at Kent State during the Vietnam War which has to be a one of a kind item. I love history, and wish I had the $$ to buy some of this stuff!
I'm interested to see what other kind of items were being offered.

I haven't looked for rare historical items on ebay. However, I would be interested to know what kind of a "market" there is for items from WW2. My dh's grandfather gathered several German weapons. I don't even know if you'd be able to sell them on ebay or not. He also has books about the Nazis. Seems he was fascinated by that stuff. :-/
