Starting in 1928, the United States began issuing its currency in a reduced size format. People were using new-fangled "wallets," and the large size notes just didn't fit in them well. Small size notes came with many different colored seals and serial numbers, each reflecting a different type of issue: Silver Certificates were blue, Gold Certificates were gold, and Legal Tender Notes were red.
In addition, Federal Reserve Notes (green) and National Currency (brown) filled out the spectrum. Collectors have begun to realize how scarce nice condition small size notes are, and have been eagerly buying them up. With the recent changes in the designs of our paper currency, the earlier notes are all disappearing.
An outstanding example of this tougher issue, Funny Back.
Dallas District. Bright paper and strong color. Superior appearance for the grade.
Dallas District. Folding is light and still looks great.
An extremely rare 1934 mule variety of a popular North African issue. The note is well centered and the paper has wonderful eye-appeal. Seldom seen in any grade and highly desirable.
Cleveland District. Dark Green Seal.
Very scarce in any uncirculated grade with a reported printing of only 337,740.
Narrow Variety STAR note.
Kansas City District. Bold ink rests upon bright paper. A scarce star note.
