Photos and two questions
The twenty is well used. The $100 and $50 are crisp, but have been folded and the $100 has a small tear.

The Five and Ten have been folded multiple times, but still have some crispness. The two is perfect, except it's not rare.

That "x" one is better than any of my star note ones which all have obvious evidence of having been carried in wallets. The star note shown was from a relatively small run.

Q1. The second one dollar note has an X at the end of the serial number. I've read that all the letters are used in that position, but I cannot remember ever seeing one with a letter past about J. Is that X unusual?
Q2. A teller at the bank showed me a note yesterday where one of the digits in the serial number was significantly above the others. It also seemed a bit fainter than the others. Is that interesting?
