Canada 1967 Quarter 0.800 Silver MS66 PCGS ‘Stealthy Blue’. An appealing representative of these dual-dated 1867–1967 quarters with a stalking bobcat. During 1967 the price of silver rose to more than US$2 per troy ounce. In response, the Royal Canadian Mint reduced the silver content from 0.800 silver/0.200 copper to 0.500 silver/0.500 copper. This coin is certified as the higher silver content, and man, do they tone up nicely!
