Am 5. Dezember 1974 fand bei Stanley Gibbons eine Spezialauktion von Sperati "die" proofs statt. Hier wurden in 445 Losen "die" proofs aus aller Welt angeboten. Das Vorwort von L. N. und M. Williams ist besonders Interessant, hier ein Auszug:

"...One of Sperati's special prides was the production of "die" proofs. They were not die proofs in the generally accepted sense of the term, because Sperati did not use dies in the production of his forgeries; but they were like die proofs in appearence,.... Each one was signed below the design by the forger himself...."
