In 1999, the Perth Mint decided to issue a Chinese Lunar Year series of silver bullion coins, following the success of the gold versions which started in 1996. We offer the complete series of coins from their initial issue in 1999 thru today. The Lunar coins come in seven popular sizes, 1/2 oz, 1 oz, 2 oz, 5 oz., 10 oz., 1/2 kilo, and kilo (32.5 oz. - the worlds largest silver bullion coin).
