This unique 1977 $100 Canadian Silver Jubilee coin was struck on a Canadian 50c Planchet with a weight of 8.1 grams, a diameter of 27.13 mm, and is 1.93 mm thick. This is likely an intentionally made unique mint error.

The Silver Jubilee of Elizabeth II marked the 25th anniversary of the accession of Queen Elizabeth II on 6 February 1952. To commemorate this special event, the Royal Canadian Mint struck the $100 Canadian coin in 1977 with a composition of .917 gold. It was struck in proof and issued in an official Canadian government presentation box. It has a weight of 16.965 grams, a diameter of 27 mm, and is 2.2 mm thick.

Here is the regular gold proof striking of the 1977 $100 Canadian Silver Jubilee that was issued in a special presentation box.

This is one of the most spectacular coins ever released by the Royal Canadian Mint. It is certified by PCGS as "Struck on 8.1 gram 50c Planchet." It is the only known Canadian $100 off-metal struck on a Canadian 50c planchet. The only other Canadian $100 off-metal known was struck on a platinum planchet.

It is incredible that this dramatic and unique off-metal striking was discovered and subsequently sent to PCGS for authentication and grading. It is in gem proof condition. This unique proof off-metal striking rivals any U.S. Major Mint Error in rarity, prestige and value.

The only other Canadian $100 off-metal known is a 1985 National Parks Proof $100, which should have been struck in gold but was struck in platinum. It was featured on the cover of Mint Error News Magazine Issue 46.
