Hi Roland and thanks for your interest.
Both the German and U.S. wartime are highly collectible and there are some rare ones -- the last two T.R. stamps issued, one is SA and one is SS. I don't have scans of them at the moment but, I posted a cute "spoof" one below. Other allied and axis wartime stamps as well are sought after.
I had suggested to the forum that it might be a good thought to institute a new subject area dealing with this subject and, that I would volunteer my time to moderate it, but it was a no go.
