David Akers (1975/88): A number of proofs exist. Since a proof was in the presentation set made for the King of Siam, it is probable that there were also proofs in the sets made for the Imaun of Muscat and the Emperors of Cochin-China and Japan. A few others were undoubtedly struck, and therefore it is possible that as many as ten proofs were minted in all, although not that many are known to exist today.
