I have a 2006A US $ 100 bill. When I asked the question in a suburban bank branch, probably over a weekend, the employee * trying to move the line faster told me that she could no longer be used. I was surprised and disappointed.
At home, I did a quick web search and found the US Treasury web pages on the US $ 100 bills.
Most importantly, ALL money from the United States is worth its face value. Period. The bank employee was wrong. It is never removed. Any invoice of US $ 100 is worth $ 100. Details on how to identify a legitimate invoice are available on the website.
My 2006A series is from the 1996-2013 era. It has all the security features and recognition marks. I plan to come back and train them on the subject if they do not accept the invoice.
1] Safety thread: A thread embedded in the paper indicates "USA 100", to the left of the portrait of Benjamin Franklin. Visible from both sides. Said to glow pink in UV light.
2] A water mark that echoes the portrait of Franklin on the far right of the note. Again, hold it in the light, its visible from each side.
3] The "100" printed in the lower right corner on the front side of the ticket color changes from green to black depending on the viewing angle. Seems like a sparkling close-up.
4] The "100" printed in the lower left corner of the side of the face is micro-printed "USA 100" instead of hatching to give it a "gray" appearance.
5] "UNITED STATES OF AMERICA" are micro-printed on the edge of Franklin's lapel.
6] Printing is in 3D – Treasury and mint seals are embossed and can be recognized on the back of the bill, as are the "hundred dollars" and the bottom "100" and "100" on the side of the face.
* One who politely asks, when a line forms, "What can we do for you today?" that is to say, "Can I get you out of this line in one way or another?", or "Is there a chance that what you want does not require one of the 2 service tellers?
