OK, thanks for the reply and it leads directly to what frustrated me. I did spend some time on that site before I posted.
So, I grabbed a bill at random. It is a 1973 one dollar bill, ACC2117938.
I looked up that year and denomination from your link, and I posted the results in a snip below.
Which one of the listed numbers is mine? Mine starts ACC and none on the list seem to.
I believe I'm making either a rookie mistake, an idiot mistake, or some unfortunate combination of the two, but I still do not see my bill.
