The numbers in the table are the first and last notes printed in the given month for the given FRB. Colors indicate notes printed at Washington, DC or Fort Worth, TX. All serial numbers in this series begin with K. Serial numbers above 99200000 are not used; thus for example KB99200000A is followed by KB00000001B.
Why Series 2006A? Since these notes have the same design and signatures as the previous Series 2006, there has been some puzzlement regarding the use of the Series 2006A designation. In response to inquiries, the BEP provided the following explanation:
When NXG [NextGen, i.e., colorized] $100 production halted due to sporadic paper creasing, the BEP went back into production of NCD [New Currency Design, i.e., 1996-generation] $100s to meet the continuing high demand for this U.S. currency denomination. With the NXG $100s bearing a new series year and new signatures, a decision was made to retain Series 2006 and Cabral/Paulson signatures on the NCD $100s. The A was added to the series to distinguish between the different production cycles.Even so, the use of the Series 2006A designation appears to be a departure from past practices, since other series have resumed production after much longer time gaps with no change to series designation.
