Hi
The Scott Catalog for R65, the 70 cent first issue revenue series stamp, also lists a plate variety as a crack plate.
I searched this website, what little I could find, if I read it correctly (?), most members think this is not a plate variety but is an Ink Smear.
See my camera images, and the arrow(s) pointing to the Area of Interest (AI).
My question to all members, what is your opinion, is the Scott reported plate variety cracked plate, or maybe you believe it is an ink smear, or maybe your opinion is that it is something else?
If your opinion is its something else, what do you think it is and what caused it?
My first camera image is the AI for this item in question, see arrow(s).

My second camera image is the AI for the location without the item in question see arrow(s).

While my camera images are not very clear (difficult to focus), the images are functional.
Bottom line, what is your opinion, is the item in questions a cracked plate, or maybe ink smear, or maybe something else?
