The BEP released the January 2016 Production Numbers yesterday. Only one new star note printing this month:
$20 - Series 2013
MA 00 000 001* - MA 03 200 000*
There isn't much interesting to say about this. It is the first, full run from the Boston (A) FRB.
For $20 series 2013 notes in general, the New York (B) and San Francisco (L) districts are the ones you want to look out for. Only 320,000 and 640,000 notes have been printed for those districts so far, respectively. Unless more, larger runs are printed in the coming months (which is totally possible), these notes will be very hard to track down long-term, especially in uncirculated condition.
