I looked on a couple different star note reference pages and couldn't find this run anywhere. The bill is a series 2006 hundred HF00332765* Just wondering if it's worth keeping if it's a small run. pretty crisp but someone wrote 100 on it so if it's not a small run I won't bother keeping it. Thanks!
It's from a run of 1,280,000 notes, which isn't too short--but it was the only run printed for the Atlanta district, so the HF..* is the scarcest star for the 2006 $100 series. See here for the details.
