This specimen was part of lot 1071 in Ponterio sale 173 (New York, January 2013), where it sold for $1,998. The catalog description noted, "AUSTRALIA. 4 Piece Proof Set, 1955. Melbourne Mint. KM-Ps16. Mintage of only 1,200 sets. 4 pieces in set. All are certified, the Penny is PCGS PROOF-65 RD Secure Holder, the 3 Pence is NGC PROOF-66, and the 6 Pence and Shilling are both NGC PROOF-67." The regular issue is common but the proofs are not. The type was struck in large quantities 1955-64 and was the last sixpence struck in Australia. An earlier type, struck 1953-54, featured a slightly different obverse legend, "ELIZABETH.II.DEI.GRATIA.REGINA." Sterling coinage ceased after 1964 and in 1966, the Australian dollar was introduced.
Sterling coinage was struck for several countries besides Great Britain, including Australia, New Zealand, South Africa, Southern Rhodesia, Fiji and New Guinea. All converted to decimal coinage in the 1960's.
Recorded mintage: 14,248,000 plus 1,200 proofs.
