Postal notes were the specialized money order successors to the United States Department of the Treasury's postage and fractional currency. They were created so Americans could safely and inexpensively (for a three cent fee) send sums of money under $5 to distant places. Postal Notes were privately produced by three different firms in six design types during three four-year contracts. Developed under Postmaster General Walter Q. Gresham, they were first issued at the nation's post offices on Monday, September 3, 1883. Numerous "first day" souvenir notes have survived. Government officials, wary of the continuing problem of postal theft, initially mandated that the notes could be cashable only in the city named by the purchaser. Engraved and printed by the Homer Lee Bank Note Company, the first two designs (Types I and II) had a space for the postal clerk to indicate where the note was being sent. If stolen en route, the note had no value, as it could not be cashed in any other city. All Postal Notes were printed on a watermarked security paper produced by Crane & Co. that features a unique watermark. Type I notes were printed on a yellow security paper blank that was about 10% larger than all subsequent issues. Type II and later notes were printed on a creamy white security paper. In January 1887, Congress changed the applicable law. Rather than being cashable at only one named post office, it decided that newly issued Postal Notes could be cashable at any money order office – the system's larger and busier offices. To comply with the new law, "Any Money Order Office" was rubber-stamped or hand written in place of a specific paying city on the Type II forms. These notes are called Type II-A. To comply with the law, Homer Lee's engravers added the words "ANY MONEY ORDER OFFICE" in a level line into the second design's printing plates. Due to the short period of time between the passage of the new law and the start of the second production contract (which Homer Lee did not receive), few post offices ordered and issued Type III Postal Notes. The American Bank Note Company of New York was the winning bidder for the second Postal Note engraving and printing contract. Thomas F. Morris, creator of the acclaimed designs for U.S. currency and stamps, as well as stock and bond certificates, etc., was assigned to
