I'm trying to identify the mark on the back of this note (bottom left). Was this a counting mark stamped by the bank? And would something like this affect the value of the note positively or negatively?
I have seen at one time or another literally thousands of $100 notes with some form of Chinese or Arabic character stamp. They are used by bankers, money changers, casinos, etc - anybody handling money as a verification that the note was checked out and is good.
So back to my other question, then. How would this affect a note's value? I can only assume negatively -- but how significant do you think on an unc note?
On a Chinese note, I am not sure, but I know on American notes value plummets. The marks are annoying, especially when you are trying to acquisition large amounts of cash that is mark free, damage free etc for taking overseas.
