Message:: [QUOTE="Numbers, post: 2949098, member: 11668"]The standard print run for star notes is 3,200,000 notes.  That's 100,000 sheets of 32 for most denominations, or 64,000 sheets of 50 for $1's. When they print a partial run, they still reserve a full 3,200,000 serial numbers for it, so the next run still begins at a multiple of 3,200,000 (plus one).  So for example run 2 always begins at 03200001, no matter how many notes were actually printed in run 1.  For quick reference: run 1: 00000001-03200000run 2: 03200001-06400000run 3: 06400001-09600000run 4: 09600001-12800000run 5: 12800001-16000000run 6: 16000001-19200000run 7: 19200001-22400000run 8: 22400001-25600000run 9: 25600001-28800000run 10: 28800001-32000000run 11: 32000001-35200000run 12: 35200001-38400000 and that's as high as they've ever needed to go since the 3,200,000-note star runs have been standard.  It's a convenient system, because you know which run a given note belongs to without having to know the lengths of all the partial runs.  For example, Hommer's note 11269446 must come from run 4, no matter how many of the previous runs were partial or how many notes those runs actually produced. In the case of the 2013 $1 B..* notes, the duplicated serials (printed at both DC and FW) were the first 250,000 serials of run 1, plus all of runs 2 and 3.[/QUOTE]
