What, when, why, where, and how?
What: the coin is an Australian 50 cent coin. Austrlaian 50 cent coins are normally dodecagonal (12-sided), and this coin is no exception. Unlike in the United States and Canada, 50 cent coins are very commonly used in circulation here in Australia. This coin is included in a "philatelic numismatic cover", or PNC. Australia Post and the two Australian mints (Royal Australian Mint Canberra and
Perth Mint) have collaborated and issued these joint coin-and-stamp items since the early 1990s. As such, it is considered an "official product" of the Royal Australian Mint and thus, the PNC is OGP.
When: 1995. Although it is only obliquely referenced on the coin and the FDC, the coin is in commemoration of the 50th anniversary of the end of WWII.
Why: The personage depicted on the reverse of the coin is Sir Edward "Weary" Dunlop, who had died just two years prior to the coin being issued. As such, he was considered to be a worthy subject to symbolize the "end of war"; as one of the relatively few survivors of being a Japanese POW, he lived to tell the tale of his ordeals, and other survivors testified to his efforts to preserve life and hope during captivity. His military career is summarized well on the PNC insert card containing the coin.
Where: PNCs were (and still are) sold through both the Mint's retail outlet and through post offices. Due to the close collaboration between Australia Post and the Mints, new coinage issues (not just PNCs) can frequently be purchased from Post Offices. It should also be pointed out that though this coin was released as a PNC, it was also issued into general circulation as a circulating commemorative coin - hence the high mintage reported on Numista. The coin is therefore more valuable while still intact in the PNC, since removing it turns it into "just another Weary Dunlop 50 cents".
How: Once a decision is made to jointly release a PNC product, Australia Post usually creates a new stamp design specifically for release alongside the PNC. These 45 cents Weary Dunlop stamps were available for purchase as postage stamps, just like any other commemorative stamp issued by Australia Post. So in this case, neither the stamp nor the coin are "available nowhere else". As such, this PNC isn't one of the more highly sought after PNCs in the Australian series. In contrast, for most of the PNCs issued in the past decade or so, the coins contained in the PNC are NOT issued for general circulation and can ONLY be obtained from those PNCs or sometimes from other NCLT sources.
Trivia time: Australia Post usually tries to assign a "significant or meaningful" locality as the postmark printed onto their PNCs and First Day Covers. In this case, the locality chosen is St Kilda Road, in Melbourne. The most prominent feature of this locality is the Shrine of Remembrance, one of Australia's largest and most significant war memorials.
