![]() Also, the sample area on the stamp that was presented to the beam covered the entire area inside the circle of the scepter and darkening only occurred where the offset impression should be. “The spectra that were obtained show that the offset vehicle is definitely present. “This technique was then applied to the area where the orange offset impression should be on the upper-right stamp of the submitted plate block and to a portion of the selvage beneath the lower-right stamp where the phosphor tagging is present. Along with this we also noticed a darkening of the offset vehicle when exposed to the infrared radiation. “We were able to obtain a specific spectra for the offset vehicle on paper with the tagging and adhesive when compared to a spectra of the paper tagging and adhesive. To suitably conduct these experiments we obtained the material used to formulate the vehicle on the offset portion of the Copernicus stamps. The purpose of using this technique was to determine if the vehicle from the offset ink remained on the stamp. “To determine if the stamps you submitted were altered we decided to use a non-destructive infrared spectrophotometric technique. Here, excerpted from the BEP’s opinion, is their reasoning: When the printing experts at the BEP took another look, they were surprised to find that indeed the original find was not genuine. So, he took the unusual step of returning the original find to the BEP together with his experimental errors and asked it to revisit its opinion. But Schiff was always as concerned with legitimacy as he was with his livelihood. Schiff could have accepted the BEP’s opinion, as certainly the buyer would. ![]() But that was not the case in these experiments. Usually there is telltale damage to the tagging and/or the gum when a color is removed from a stamp. In the meantime, his office staff, as a matter of curiosity, experimented with normal examples of the stamp to see if they could remove the sun without damaging the stamp. He sent it in, the BEP looked at it and pronounced it genuine. Schiff thought the best place to rule on the legitimacy of the error was the Bureau of Engraving and Printing, where the stamp had been printed. However, the plate block was purchased contingent upon it receiving a good certificate of authenticity. ![]() Its first appearance in the form of a plate block realized what Schiff called “the tidy sum” of $1,760. (1931-2017) ran an auction firm that specialized in errors, so it was no surprise that the new missing-sun error migrated to him to sell. The latter didn’t happen, but shortly after the stamps were issued, reports surfaced of examples with the sun omitted.Īt the time, Jacques C. The illustration of Copernicus was engraved in black ink, while the sun was printed by lithography in yellow orange, setting up a situation where one part of the printing could be missed or inverted. The design of the 8¢ stamp shows Copernicus holding a representation of the sun as the central feature of the universe. He published his theory that the Earth revolved around the sun rather than the other way around in 1543, just a few months before his death. In 1973 the United States Postal Service issued an 8¢ stamp honoring the 500th birth anniversary of Polish astronomer and mathematician Nicolaus Copernicus (Scott 1488).
