In October 2007, the Million Dollar Coin was certified by Guinness World Records to be the world's largest gold coin. The coins are manufactured at the Mint's Ottawa facility, where the Mint operates world-class gold and silver refineries, securely stores gold bullion and mints all Royal Canadian Mint gold bullion products and collector coins. The reverse features an elegant, hand-polished maple leaf design by Royal Canadian Mint artist and senior engraver Stan Witten, and the obverse bears the effigy of Her Majesty Queen Elizabeth II by celebrated Canadian portrait artist Susanna Blunt. The coins are both adorned with a maple leaf and boast 99.999 percent purity, a notch above previous purity peaks of 99.99 percent.
