1st Issue Revenue Question

Depends a lot on the color of the stamp in question. also, it all just depended on what day it was, which company had just delivered the paper, and what stamps happened to be printed that day. Once you get to about mid 1864, the paper thicknesses began to vary a great deal more, and after 1865 it could change a lot.
The reason that the scarce and rare part perfs and imperfs can be told in part by the paper is because few sheets were printed, and they were usually all done at the same time. So the shade, impression, and paper were all the same.

This is great to know, Bart! I currently have some questionable part-perfs, and it would be nice if I could validate their authenticity by the paper they're on.



This went way over my head Don
I'm more of a hands-on type of learner..

I forgot about this other piece that I pulled from the same set but placed aside to study later... for obvious reasons.




It has the same "brown sandwich bag" type of paper and the same dimensions.
The ink is also the same hue of 'smoky blue', which also doesn't saturate into the paper surrounding the design.




The paper on all three looks crisp, as if it's how they were originally made.
Does anyone have any examples of paper and inking that look similar?
