Hello, I am currently looking at buying a nice uncirculated 1899 Black Eagle, and I found two PMG 64's. One, priced a little more, has Exceptional Paper Quality designated, while the other does not. What are the differences between EPQ and non EPQ notes? The only thing I can think of is that the note might be faded, but that's it. I am not asking specifically about the note I'm interested in, I am talking about in general, what separates EPQ from non EPQ. Thanks :smile
