I have a copy of what looks like Scott #35. I thought it was fake at first, because the paper is exceedingly white, see stamp to the right (a normal copy is to the left for comparison):

If it is a fake, the printing looks amazingly well done. Here are closeups of the front and back:


What do people think?
Did someone bleach this to a bright white? Or did they all start this white, and most have degraded?
How do you think that would affect the value?
thanks
