Australia's Perth Mint has created the world’s biggest gold coin—more than a ton of 99.99% pure gold, the Sydney Morning Herald reports. The coin’s face value is $1 million Australian dollars—just over $1 million American—but it’s worth more like $57 million American. At 31 inches wide and almost 5 inches thick, the coin is “the pinnacle of ingenuity and innovation,” said the CEO of the mint. One side features Queen Elizabeth, the other a kangaroo, notes the Telegraph. (More Australia stories.)
