The Queen is on a ten-day tour of Australia and will be at the opening ceremony for the Commonwealth Heads of Government Meeting this week.
"To cast and handicraft a coin of this size and weight was an incredible challenge – one which few other mints would even consider,” said Perth Mint chief executive Ed Harbuz, according to The Telegraph. Here's Harbuz posing with the coin.
