100 Dollars - Elizabeth II Alexander Graham Bell

Issued in 1997 to mark the 150th anniversary of Bell's birth, this coin commemorates the inventor who developed much of his telephone work in Brantford, Ontario — a fact Canadians have historically been more eager to claim than Americans. Bell himself held Canadian citizenship and died at his Cape Breton estate in 1922.

The .583 fine gold content places this outside standard 14-karat territory by a fractional margin, a specification the Royal Canadian Mint used selectively for its commemorative $100 series during this period to balance bullion value against face denomination.
