Where does one place one's redemption stamp on a FRN? I've seen front and back placement. Ultimately, I do not think location is that important, only showing the fact that redemption has occurred.
Personally, I place mine on the front and over the legal tender language for two reasons.
1. Because of this link from the SF fed bank. Scroll to bottom and under did you know to read the second bullet:
That is why I stamp the front of each FRN.More than half of a dollar bill is considered legal tender, and only the front of a dollar bill is valuable. If you could separate the front of a bill from the back, only the front half would be considered "money."
2. I choose to place it over the legal tender language because in my mind I am changing the nature of the FRN and therefore potentially altering the validity of the legal tender language.
