This remarkable coin from the Wedge-tailed Eagle program is the first Australian bi-metal coin to be released by The Perth Mint in more than a decade.
Showing samples being struck for test purposes, the clip demonstrates how two precious metal blanks in the form of a ring and a centrepiece are effectively bonded together during the coining process.
Made from pure gold and pure silver, the blanks are expertly crafted by our minters to weigh precisely (and certainly no less than) 1/2oz of pure silver and 1/2oz of pure gold. They’re individually loaded on the press where the centre fits snugly inside the ring.
Compressed between the obverse (heads) die and reverse (tails) die, the blanks are then stamped with their designs. Under pressure, the metal tries to spread outwards, but is constrained by a reeded ‘collar’ – ensuring the softer gold is squeezed tight inside the silver ring.
The stunning result portrays John M. Mercanti’s extremely detailed representation of a Wedge-tailed Eagle, Australia’s largest bird of prey, on the new coin’s gold proof centerpiece. It’s seamlessly contained within an inscribed silver border also struck with a proof finish.
A long-awaited addition to the Mint’s sought-after bi-metal issues, the stunning release has a mintage of just 750 and comes beautifully packaged in a timber presentation case.
