US stamps & autographs are not my specialty, but prices are always subject to quality, demand & supply. If you’d place the items for sale here in Europe, I’m pretty guaranteed you’d get peanuts compared to what US markets could bring.

The fact that stamps has a signature does not definitely add it’s value in philatelic world; it’s nothing but a curiosity and most would throw the stamp to junk bin. But for autograph collectors it’s a gem of course, A quick Google search brought up a block of four U.S. Army 3-cent stamps with Doolittle signature priced at 500$, singles were found at 70$.

RE, Eleanor Roosevelt free franked envelope – same advice as above. A quick search on eBay brought up several (sold) matching items in range of 25-100$.

I bought a stamp 20 years ago at a coin and stamp show in Seattle. My stamp had General Jimmy Doolittle’s autograph on it. plate # 21695.

Have no idea is worth or whatever..could you fill me in on info on this historic treasure I have. I also bought a letter and the free mailing envelope with from the White House by Mrs. Roosevelt. Clue me in on what I have please.

Thank you, Jim Redland in Washington State

Sadly here in Germany all stamps issued before 2000 became invalid with the introduction of the Euro. You can’t evenen exchange them for valid stamps any more.

When they were issued it was said they would be valid “forever”, but in this case “forever” lasted only some decades.

The new stamps are also valid “forever”. We will see how long “forever” will be this time …
