My mom recently gave me a $1 with the last two digits in the serial number 88, because it was the year I was born. The actual serial number is F F70701788 F. I also have the one before it, F 70701787 F. I thought nothing of this really, other than a keep sake, until I looked at the date. It said Series 2003 A. I had to do a double take because I had never seen a 2003 A series dollar before. I have seen tons of 2003, but never a Series A. Whats the difference between a regular 2003, and a 2003 A?
Only one signature changed on the note from the 2003 to the 2003A. Had both changed, it would have gone from 2003 to 2005.
Yes, if one signature changes, the series 2003 becomes 2003A. If one of the signatures changed again, it would be 2003B, and so on. A 2003A is worth nothing over a dollar (unless, ya know, a star or radar or the like). I spend 'em.
If the Treasuers signature changes they change the series letter. If the Secretary of the Treasury's signature changes the change the series date. It has been that way since I believe the late 1980's. Before that the series letter changed when either signature changed and the date changed when BOTH signatures changed.
