For the first time, a non-denominated rate-change stamp was issued and then re-issued later in the year, bearing the first-class rate denomination. Once again, the stamps were printed three different ways by different companies: United States Bank Note Corporation for the sheet, KCS Industries Inc. for the booklet, and Stamp Venturers for the coil. The coil, however, had "slit perforations" or rouletting, giving it an imperforate appearance.
