three leading zeros itself is not a very low serial. 4 or more zeros is starting to get low. I do try to keep any $1 note with 3 or more though - not becuase they will ever me worth much... i just like seeing all those 0's what is the series date? I can then look up to see how rare the district might be
If the serial starts with an E, it has to be Series 2004. The EJ..* $20 had a printage of 3,200,000 notes--actually one of the lower totals for the 2004 $20, but still not really low.
Sprry about taking so long, and thanks for the info. The date is 2004 and the serial number does start with EJ. I guess i'll keep my eye out for 4 or more leading zeros, from now on.
