I know this topic has been left alone for awhile, and, at risk of beating a dead hoarse....
about a month ago, my boss received with his weekly withdraw from the bank, 2 crisp bricks of 5's, one was quite mixed up, although all AOT's, it consited of 3 or 4 different consecitive lots. I assumed that it must have gotten mixed with other bricks at the bank. The other brick was AOS, I don't recall the numbers, other than about half way through, I found AOS4850416, assuming it an insert, I checked my list, and found it listed as such in a 40k range. I promptly gave my boss $5, and bought the note for my collection.
I realize there is a possiability that this note was mixed in the brick, as I did not get the brick from a complete block. and although I don't remember the other serial #'s in the brick, I do rember noticing that it had the same fn, bn as the rest of the brick.
