1916-17 5¢ Washington, blue
US #466 was one of the first stamps on unwatermarked paper and was largely overlooked at the time.

On October 17, 1916, the US Post Office issued a 5¢ Washington stamp. The stamp had small changes from previous issues that went overlooked by collectors, so few were saved. Plus, this stamp spawned some famous errors…

In 1916, the Bureau of Engraving and Printing (BEP) began producing stamps on unwatermarked paper. With the United States already close to a wartime economy as World War I raged in Europe, the lower cost for the paper added up to big savings for the Bureau. However, single line watermarks on previous stamps were often quite hard to identify, and collectors were slow to recognize that a new type of paper was being used.

Adding to the confusion was the continued use of 10 gauge perfs. A year earlier, 11 gauge perforations had been introduced, and the collecting community expected to see new stamps with that gauge. But in another cost-cutting move, the BEP continued to use the 10 gauge perforating rollers until they wore out completely. The Series of 1916 Washington-Franklins used the same design as previous stamps. Since it was easy to miss whether it was new unwatermarked paper or paper with faint single marks, many collectors overlooked these stamps when they were first issued.

The 1916 5¢ Washington, #466, was among those stamps. Issued on October 17, 1916, the 5¢ Washington was primarily used to pay the postal rate for foreign mail. Because the BEP was planning to change 11 gauge perforating wheels soon after this stamp was issued and not wanting to print a lot of stamps that would soon be made obsolete by a new method of production, the BEP kept production of US #466 limited.

Two famous errors also occurred during #466’s production. Both were 5¢ red stamps (that should have been blue) that were mistakenly printed on sheets of 2¢ stamps. So, how did 5¢ stamps find their way onto 2¢ stamp sheets? This story begins in 1917, during the height of World War I, with an overworked and understaffed BEP struggling to keep up with wartime demands. An inspector at the Bureau proofed a sheet printed by plate 7942 of the current 2¢ issue, Scott #463. Three of the impressions made by the plate were found to be unsatisfactory, and the inspector ordered them replaced.

1916-17 5¢ Washington Imperforate Carmine Error
US #485 is the even rarer imperforate carmine error. Stamp expert Max G. Johl called it “one of the rarities of the 20th century.” Just 50 exist and we only have one available!

To understand what happened next in the double error story, it’s important to know how these plates were produced. First a design is engraved on steel. Proofs are taken from this engraving. Once these proofs are approved, the steel of the original engraving is hardened, and it becomes the “die”. A transfer press is then used to transfer the die’s impression onto a cylinder of soft steel, known as the “roll,” which is in turn hardened. This roll is then put in a “siderographer’s” transfer press, which again transfers this image into the steel plates that are used to print the stamps. In short, a die is used to make a roll, which is used to make the printing plates.

US #505 was printed in the wrong color with the wrong perforations, creating two errors in one!

On plate 7942, the impressions for stamps 74 and 84 on the upper left pane of 100, and stamp 18 in the lower right pane were found to be defective. The worker who repaired these three impressions accidentally replaced the 2¢ designs with 5¢ designs. Considering that the “5” on the transfer roll is very similar to a reversed “2”, it’s not surprising this mistake was made. Because of the great strain placed upon the overworked employees of the BEP, the proof sheet was not inspected again. Production continued, and the sheets were eventually distributed to Post Offices.

Soon blocks of twelve containing a vertical pair of 5¢ stamps (sometimes referred to as the “double error’) and blocks of nine containing a single 5¢ stamp (often referred to as the “single error”) began to appear. Although the Post Office recalled all the sheets bearing the plate number 7942, some had already been sold and put into circulation.

When the sheets created from plate 7942 containing the 5¢ error stamps were sent to the perforation stage of production, most of the machines at the BEP had been changed to provide a perforation of 11. In fact, most sheets containing the 5¢ errors were perforated with the 11 gauge machines, and are thus much more common than the perforated 10 type. The perf. 10 stamps were given the Scott #467, while the perf. 11 stamps were given the Scott #505.

  1. Never liked the Washington/ Franklin stamps. Hard to id as a kid and now too expensive to buy. Sad redundancy for USA in the early 20th century. All the great subject that could have been used. I miss the old time walk in stamp stores also. Too bad stamps are so expensive these days for kids to collect, and ugly stamps too. I did like reading the article on the 1916 errors.

  2. Thank you for giving a full explanation of the very unusual anomaly (Error) of 2 five cent Washington Stamps imbedded in a block of two cent stamps.
