Prince George’s Oct. 23 christening, an intimate private ceremony at the Chapel Royal in St. James’s Palace, was cause for celebration. Breaking with tradition, Prince William and Duchess Catherine chose seven godparents for their 3-month-old son, six of whom are non-royals (William’s cousin Zara Tindall is the only royal in the group) – in contrast, William’s six godparents include titled nobility such as former King Constantine II of Greece and Princess Alexandra. Most notably, Prince George’s christening is also the first for which the Royal Mint has issued a commemorative coin. Ranging in price from 13 pounds (about $21) for the basic nickel design to 50,000 pounds ($80,000!) for an intricate one kilogram of gold, such a memento only comes about for the most important tributes. Its inscription reads, “To celebrate the Christening of Prince George of Cambridge 2013,” with a design of two cherubs playing the harp.
