This is kind of interesting when you consider it, because eventually these lower grade notes will be discarded/destroyed by the bank/deteriorate on their own, making them ultimately scarcer and more valuable. Although this might take longer than we will be collectors.
Certainly most people (non-collectors) would likely respond favourably to receiving a 1937/1954 $100, and have an impulse to save it (how many non-collectors have shown you an essentially valueless 1954 $1 in VG condition), speaking on a certain level of their collectability, and yet as collectors, they are so available, we are disinterested.
