It's not a word. I just made it up. To me, everything but that 1st $5 is worth holding on to. Not because they're especially valuable, if at all, but because they are different, and they are what we call Show and Tell, is made of. It just depends on what you like. I collect * notes. Many people do. Also what is called " Fancy Serial Numbers ". Remember, condition and age are very important, in that order.

Like many types of collecting, paper money collecting values are closely tied to condition. Most, if not all of the notes, are not in collectible condition. If you collect strictly from circulation, and like the notes, then keep them, except maybe the $20. Spend that for sure. Don’t let the series date mislead you.
