Wrong planchet - Errors and varieties
This error appears when a coin is struck on a planchet not intended for this particular design.
Planchet from another denomination
Because they are stuck in the feeding tubes, badly stored or any other reason, some of these planchets can be struck with a design from another denomination. Most wrong planchet errors fit in this category. Examples:
- 1 cent 1979 on a 10 cents planchet
- 5 cents 1978 on a 10 cents planchet
- 25 cents 1982 on a 10 cents planchet
Planchet from another country
Since its opening in 1908, the Royal Canadian Mint has produced coinage and planchets for 89 countries (90 counting Canada).
This category includes planchets from a non-circulating coin, intentionally produced at the Mint by an employee, a mix of the previous categories and more.
- 1 dollar 1969 struck on a 50 cents silver planchet
- 1 dollar 1970 struck on a 22.8g gold planchet Only six pieces are known of the ten pieces originally struck. Four were melted.
For some reasons, metal strips, blanks or planchets from previous years can be mixed up. The 5 cents 1944 Tombac coin production was mostly intended before the switch nickel with chromium plating composition.
