20 Dollars - Charles III Moon phases

The Moon Phases series is one of the Royal Canadian Mint's more technically demanding annual programs, requiring precise application of black rhodium to specific relief zones without contaminating adjacent fields — a process that the RCM has refined across multiple collector series since the mid-2010s. Each coin in the KM#3593–3599 run corresponds to a distinct lunar phase, making this a seven-piece set rather than a single issue.

Charles III's effigy on Canadian coinage was confirmed following the Accession in September 2022, with the RCM adopting the Jody Clark portrait — originally commissioned for the late Queen — as a transitional obverse before the new Gough portrait entered circulation-issue production.
