AOF has two dates and appears on two different $5 Issues.
1st AOF run appeared on the 2002 issue of the $5 all dated 2001
last note printed was #3799999
2nd AOF run appeared on the 2006 issue and printed date 2006 and all above 3.8M
They are both issued as regular notes, fully circulated, not scarce and widely available. I don't think any AOF inserts were issued
All AOF notes are not worth that much below UNC
Still rather nice to have one of each though in UNC.
