1975 Papua New Guinea Complete First Official Coinage Proof Set. This is the full original set of Papua New Guinea’s first national coins, issued in 1975 to celebrate the country’s independence. All eight proof coins are sealed in their official First Day of Issue Cachets with commemorative stamps and postmarked on the first day of public issue. Every certificate is signed by Honourable Michael T. The first Chief Minister (and later first Prime Minister) of Papua New Guinea. The set comes in the original black leatherette presentation album with the official descriptive insert. History: Papua New Guinea gained independence from Australia on 16 September 1975. These were the very first coins issued by the new nation. The Franklin Mint struck the proof versions under official authority. The designs showcase the country’s unique wildlife and national symbols. This particular format – proof coins paired with first-day covers – makes it a dual collectible for both coin and stamp enthusiasts. 10 Kina – Bird of Paradise with the Southern Cross.
