Are the two new bills of the $ 100 which were first presented to the public has collectors value added ? And Are they supposed to give a nice premium ? New $100 Bill Displayed at ANA World's Fair of Money - Link : New $100 bill at Convention in Rosemont - Link :
They are not "supposed" to do anything. They might command a premium, but then, they might not. Can you afford to sit on a C note waiting for the possibility of a premium?
Well, it is also a star note. If your not hurting for cash, I would keep it. I got one from the bank myself and added it to my star note book. So I think it would be worth saving.
On collecting bills I collect only new 100$ bills and for the first two bills which were presented in public I was happy to pay a nice premium!
