Tagging-omitted errors of U.S. 2024 Flags coil stamps discovered in mixture

Newly discovered tagging-omitted errors of the United States 2024 Flags coil stamps were reported to Linn’s Stamp News in late January.

The stamps (Scott 5875-5878) were printed in rolls of 100 by Banknote Corporation of America in Browns Summit, N.C.

One of the tagging-omitted errors (of Scott 5877) is pictured above. That stamp, which is tied on piece, bears plate number B1111 in the bottom margin. The “B” prefix is shorthand for the printer.

Robert Thompson of Texas, a specialist in modern U.S. coil stamps, told Linn’s he obtained the new tagging-omitted errors from another collector who found them in a mixture and believed the stamps were counterfeit because they lacked tagging. Many modern U.S. counterfeit stamps are not tagged.

I know they are real [tagging-omitted errors] because they have the micro bridges along the top and bottom,” Thompson said. “To date there have not been any fakes found with micro bridges.”

According to Thompson, coil rolls of 100 printed by Banknote Corporation of America are produced in sticks of 10 rolls that are connected by small micro bridges of paper about 1 millimeter apart on the straight edges at the top and bottom of each roll. A single roll can be separated from the stick by breaking the micro bridges.

Thompson said he submitted the new tagging-omitted Flags coil stamps to the Philatelic Foundation in New York City for authentication in late January. On Feb. 6., he notified Linn’s that the Philatelic Foundation had confirmed that the stamps are genuine tagging-omitted errors.

Based on Thompson’s analysis, the Scott editors determined that the new errors will be listed as Nos. 5875b-5878b in the 2027 Scott Specialized Catalogue of United States Stamps and Covers to be published in the fall of this year.

Numerous tagging-omitted errors of other U.S. stamps have come to light in recent years.

Linn’s Aug. 5, 2024, issue carried a story about a new tagging-omitted error of the 2023 Freedom Flag coil stamp (Scott 5789A), which Banknote Corporation also printed in rolls of 100.

In the Feb. 12, 2024, issue, Linn’s reported the discovery of a tagging-omitted error on the U.S. 1981 nondenominated (18¢) B-rate Eagle booklet stamp (Scott 1819).

The new listing for Scott 1819b in the 2025 Scott U.S. Specialized catalog reads, “Block of 8, tagging omitted” along with a footnote stating, “No. 1819b is found on an Artmaster cacheted cover with a first-day postmark.”

In the Aug. 8, 2022, issue, Linn’s announced the discovery of a tagging-omitted error on the U.S. 1991 29¢ Comedians booklet stamp (Scott 2562) honoring Laurel and Hardy that came from a booklet pane of 10 containing two each of the five different 29¢ Comedians stamps (2562-2566).

In addition to the aforementioned Laurel and Hardy stamp, during the past several years, Linn’s has reported tagging-omitted errors of the 2017 nondenominated (47¢) Love stamp (Scott 5155), 2022 nondenominated (58¢) Flags coil stamp printed by Banknote Corporation of America (5656), 2019 nondenominated (55¢) Flag coil stamp printed by Banknote Corporation of America (5343), 2022 nondenominated (58¢) pink Love stamp (5661), two of the four 2022 Mountain Flora stamps (5676 and 5677), and one of the four 1986 22¢ Ameripex ’86 panes of nine (2219).
