Hello KD....
Since you work at a bank and get to go thru many many notes you have a better advantage of seeing what is there than most other folks.
I also see you ask alot of questions based on what do you collect or would you collect this or that? The questions are great ones so please do not take this the wrong way....LOL
From what I gather about you is that you are really undecided on what it is you would like to collect or that you may want to filter through what might be worth more than face....who would'nt??
The question you should ask yourself is what do I, KDKenn want to collect?
You see, every collector has his/her own agenda for what is important to them and what makes them feeel graet about their collections.
With the opportunity you have in front of you, I would be looking at a small size collection of stars, binaries, radars, and possible errors.
Find the direction and the notes will make them selves known to you.
Keep up the search and go to
www.banknotebank.com and setup a viewing area fro your notes!!
Best of luck to you...
Kind regards,
RickieB
