1977A $1 Star Notes... Print Run Madness

http://www.uspapermoney.info/serials/f1977as.html
2,560,000 6 runs is what I read,but I have trouble with the info most of the time.Also have you checked to see if your note is the Natick note? A similar experiment took place in 1981, when the BEP produced a few print runs of notes on Natick security paper. The notes involved were Series 1977A $1's with serial numbers E 768 00001 H through E 806 40000 H and E 070 52001 * through E 076 80000 *. (Note that many references incorrectly list this star range as Philadelphia instead of Richmond.) One run of $10 star notes was also included in this paper test, making it the only experimental printing so far not restricted to the $1 denomination.

Thanks, John1 and Steve. Those are going to take a couple of reads through (at least) to sink in.

Yes, the run size is 8,000 sheets, for a total of 256,000 notes.

The BEP uses a standard run size for its print runs. A certain range of serials is assigned to a run based on the standard run size. For example, the standard run size today for regular production notes ($1 through $20) is 200,000 sheets. The serial numbers assigned to run 1 will span 00000001 to 06400000 (32 plate positions times 200,000 sheets), serials numbers assigned to run 2 will span 06400001 to 12800000, and so on.

In the case of star notes, the standard run size today is 100,000 sheets. The serial numbers assigned to run 1 will span 00000001 to 03200000 (32 plate positions times 100,000 sheets), serial numbers assigned to run 2 will span 03200001 to 06400000, and so on.

When Series 1977A was in production, the standard run size for star notes was smaller -- just 20,000 sheets. The serial numbers assigned to run 1 spanned 00000001 to 00640000 (32 plate positions times 20,000 sheets), serial numbers assigned to run 2 spanned 00640001 to 01280000, and so on.

If the BEP determined that it didn't need to print a full run of stars, it simply used fewer sheets for the run but retained the assigned range of serials. That is, run 1 still spanned 00000001 to 00640000. But the run was simply stopped before all 20,000 sheets were serialed.

That necessarily meant that not all of the serials assigned to the run were used. In your example of Series 1977A $1 note D05853793*, it is from run 10, whose assigned serials spanned 05760001 to 06400000. But since only 8,000 sheets were printed, only 256,000 of the possible 640,000 serials were used. The notation from the US Paper Money website identifies the serials that were used:
Plate position A1: 05772001 through 05780000 (meaning that 05760001 through 05772000, the remaining serials belonging to PP A1, were not used)
PP B1: 05792001 through 05800000 (05780001 through 05792000, the remaining serials belonging to PP B1, were not used)
PP C1: 05812001 through 05820000
PP D1: 05832001 through 05840000
PP E1: 05852001 through 05860000 (the group of serials to which your note belongs)
and so on through
PP H4: 06392001 through 06400000

So run 10 was a single run. But because fewer than 20,000 sheets were serialed, this resulted in small groups of unused serials within the assigned serial range for run 10.

With JOE on the forum, I'm going to stop trying to figure out all of this.
