I know they aren't worth much but while paying out at the local grocery, the cashier asked if I minded getting all ones since he didn't have a five. I never mind, as I told him, they all will spend. When I got to the truck, I noticed that they were consecutive stars. Here's the double part: As I was putting them away in my rat hold, I was looking at some other bills that I have horded, and came to a question I don't know the answer to. I know from previous series, that if there is a change in the helm at the treasury, the series changes. Say from 1928 to 1928A to 1928B and so on......and also when there is a change in design, it will change to the year that the new design is released, (or is it when the new design is approved? ), my question is if there is no change in design or the treasury helm, does it also change when they have run the gambit of numbers?
Some of your questions can be answered here; http://www.uspapermoney.info/general/chron_s.html Scroll down to the section "A few words about series numbering"
The very last sentence in that, was what brought up my question. I was holding a series 2009 $100 up to a series 2009A $100 and there was absolutely no difference in the two, other than serial numbers.
Yes, those are definitely a strange case. There's no apparent difference between the 2006 and 2006A $100's, either. Neither the 2006 $100 nor the 2009 $100 actually ran out of serial numbers (indeed, the 2009 $100 had a fairly small printage by $100 standards), but it's possible that the BEP's decision to change the series designation when production resumed was motivated by a desire to avoid running out of serial numbers for the New York district. Series 2006 and 2006A, combined, included far more New York notes than could be numbered in a single series. And Series 2009 and 2009A, combined, are only 51.2 million notes (less than one month's typical production) away from reaching that point. In general, though, series designations are just getting weird lately. See the two different $5 series that were both labelled Series 2006, for example....
Thank you both. I'm still fairly new to paper collecting, and either learn something new everyday or find out that I didn't know what I thought I did.
