Celebrate the Year of the Horse with this stunning colored coin decorated with UV printing and struck in a beautiful proof finish with the mintage quantity limited to 9,999 pieces worldwide. Being legal tender in New Zealand, the coin displays the effigy of Her Majesty Elizabeth II on its obverse. The portrait is surrounded by the following inscriptions: the Queen’s name, the face value of the coin, its issuing country and year. A special minting technique of UV printing has been employed to create the reverse design that features a colored image of two relief horses. The name of the coin is indicated at the top of the coin. In addition to the Chinese symbol standing for the Year of the Horse, the reverse also features a gilded horseshoe, one of the most popular good luck symbols. The Chinese believe that because horses are born to race or travel, all Horse people need freedom and usually leave home young.
