I would venture to guess that in the case of these covers, a U.S. buyer
probably would not be heartbroken to not get the contents of the cover.
My opinion is that I would love to have cover like this, but would not
care if the contents (letters) were contained within, nor would I pay
extra for a cover to have the letter inside which is in a language I
cannot read. Even if it was in English, for me to pay more for contents
of a cover, it should be of important or at least very interesting
historical context. So there you have the insights of a potential U.S.
buyer... Keep your family letters and profit from the envelopes.
My .02 cents. Worth what you paid for it!
