Came across this 10.00 bill from the 2017 series and to me it looks like an inking error. There are many areas of this bill that have a pinkish tone strewn around the obverse and some on the reverse. The color looks exactly like the torch and We the people. Could this be an inking error? If so, would it be worth anymore than face?
I would need to examine it in-hand. I'm having a hard time figuring out how it got onto the back of the note. It may end up being nothing more than a post BEP stain that coincidentally matches the color of the ink used on the front of the note. Cool find, maybe.
