I received wonderful and informative responses when I posted about a proof sheet here:

Besides welcoming your general comment about this item, I was wondering if the die proof was pulled contemporaneously to the creation of the stamp plate or if such items were pulled much later for some reason by the printing organization or the Post Office.
Also a general price range of a single die price/interest comparison between the plate and die proofs. Can I assume that the die proof in this area carries the same general interest as with early US material?
