Wife brought this home from the restaurant she works at with all her tip money. She never noticed it but I picked it out right away. The star not lookup gave the following: Run Number: 1 Serial Number Range: ML 00 000 001* ↔ ML 00 640 000* Printed at DC facility in July 2014 Other Star Note Runs For Series 2013 $20 "L" FRB Range Run Size ML 00 000 001*↔ML 00 640 000* 640,000 ML 03 200 001*↔ML 06 400 000* 3,200,000 ML 06 400 001*↔ML 07 040 000* 640,000 Might just slip it into a sleeve and stash it just for the heck of it since it's not over 640k for this run.
