Silver Shield 1 oz .999 Year of the Sheep Proof The 2015 Silver Shield Year of the Sheep is the first coin in the new Silver Shield Lunar Series! This unique design stands out from all other Lunar Series on the market and keeps true to the Silver Shield spirit. The Year of the Sheep features a visceral image of two wolves eating an ignorant and docile sheep. This symbolizes the cunning men that prey upon the naive and indoctrinated masses. The 2015 Year of the Sheep is accented with the Chinese symbol for sheep. The final detail is a lonely sheep dog howling a distant warning, which symbolizes those that are aware and prepared.
