I just get them from the bank to spend them and look for Ds to fit my folder. I wouldn't like to get this many at a time anyway, though I do like the idea.
What you are seeing with this, IMHO, is the precursor to the end of the $1 FRN. Given the court decision last month - about our currency not being "friendly" to the blind and vision impared - it is a given that the Treasury will have to re-design all of the FRN's (with the exception of the $5 perhaps) soon. From what I understood, the options are to either vary the sizes of the notes or add "features" to them to comply with the court decision. I think the courts will do what the politicians couldn't/wouldn't do! From a standpoint of economy, it would make sense to quit producing the $1 FRN as there is already a suitable replacement for it already (at least that is what the gov't can say). And since the $5 would then be the lowest denomination FRN in common circulation - and would probably be OK as is - only the $10, $20, $50 and $100 would need to be modified by either changing their sizes and/or adding new features. I can then foresee the inevitable issuance of a $2 coin as well once the initial public acceptance of the end of the $1 FRN note is set.
