5 Dollars - Elizabeth II Polar Bear, Silver

Canada's bullion silver Maple Leaf program has carried the polar bear design as part of its wildlife series, though the Royal Canadian Mint has issued so many overlapping collector and bullion variants in recent years that distinguishing individual releases by reference number has become practically essential. The two RCM catalog numbers here — 203410 and 203464 — likely reflect packaging or market variants of the same strike, a common RCM practice for simultaneous domestic and international distribution channels.

.9999 fine silver was adopted by the RCM as its bullion standard in 1998, edging out the previous .9993 fineness to claim the title of world's purest mainstream silver bullion coin at the time.
