125 Dollars - Charles III Murano Monarch Butterfly

The monarch butterfly's cross-continental migration — up to 4,800 kilometers between Canadian breeding grounds and Mexican overwintering sites in Michoacán — was not formally recognized as an endangered phenomenon until the IUCN red-listed the migratory population in 2022. Canada's breeding habitat, concentrated in southern Ontario milkweed corridors, has declined sharply alongside it. The Murano designation refers to the hand-applied glass enamel technique sourced from Venetian craftsmen, an unusual subcontracting arrangement for a sovereign mint issue.
