My first post is an introduction of myself. I would consider myself a hardcore collector of small size US currency. My first introduction to currency collecting was in the late 1960s when my grandmother was actively searching for $1 FRN Barr notes. At that point I started looking at all notes. I bought my first currency book shortly thereafter.
In the 1970s I was pulling circulated $1 FRN star notes out of circulation. While none were worth more than face, I still regarded them as rare.
