On August 31, 1971, C.G. Carsey, a clerk in the Astronaut Office in Houston, typed certifications on 100 of the covers, with the aid of other NASA employees in her office. The certifications stated the cover had been on the Moon aboard the "Falcon". The covers already carried a handwritten statement signed by Scott and Irwin that they had been landed on the Moon on July 30. Carsey later stated that in signing the certifications as a Texas notary public, she only intended to certify their signatures were genuine. The question of whether Carsey had improperly certified that the covers had been landed on the Moon (something she had no personal knowledge of) was the subject of an investigation by the Texas Attorney General. With the notary certifications, the last of Sieger's requirements for the covers was fulfilled. On September 2, Scott sent the 100 covers by registered mail to Eiermann, who was in Stuttgart, where he had moved. Eiermann turned the covers over to Sieger, and was rewarded with a commission of about $15,000—ten percent of the anticipated proceeds. The remaining 300 were entrusted by the astronauts to a Houston-area stamp collector who arranged with a local printer to have an inscription stating that the cover had been carried to the Moon printed in the upper left. The printer discovered there were 298 covers, not 300; the stamp collector consulted Scott, who told him not to worry about it. One of Irwin's covers from the group of eight, with a shamrock design as its cachet, was given to Rhodes and one to the president of the Kennedy Space Center Philatelic Society; Irwin said in 1972 that he had retained the other six.
