Whao!! Dramatic coin designs. Guess the Chinese’s contributions to the world of coins are popular dragon designs and…. the lunar series coins. World’s most reputed government mints including the U.K. mint, Canadian mint through to the Australian Perth mint issue coins that honor the Chinese lunar year. This year for the first time in the U.K. mint’s history of 1,100 years, they issued silver Britannia with a privy marked rim. The privy mark on the rim is of a Chinese snake that represents the “Year of the Snake”.
