Thirty-five years of collecting have come to a head: Bob Azpiazu is selling his low and fancy serial numbered notes.

Robert is a paper money dealer, but I don't mind giving a free plug here because these notes have been a collecting passion over and above his dealing. Further, he shares his information, notably in the form of a book on $1 Federal Reserve Notes he self-published last year.

If you're looking to add some pizzazz to a small-size note collection — like a serial No. 3 1957 $1 Silver Certificate in gem uncirculated instead of a common type example — give his Azpiazu Collection price lists a look.

Two lists have come out so far; you can e-mail him at fstctycu@bellsouth.net to request them. He'll also have many of the notes at the Long Beach Expo May 31-June 2 in Long Beach, Calif.
