100 Dollars - Elizabeth II Montréal Olympics, 14k

The 1976 Montréal Olympics gold issues were the first Canadian coins struck in 14-karat gold — a deliberate compromise driven by the Royal Canadian Mint's need to produce an affordable collector piece without committing to the fine gold standard used by most sovereign bullion programs. The unusual .5833 fineness was chosen precisely to hit a retail price point accessible to the general public during the Games' fundraising push, as Montréal's organizing committee was already struggling under catastrophic cost overruns that left the city servicing Olympic debt until 2006.
