The Royal Canadian Mint unveiled its new Specimen Set 2025 this year , an exclusive collection that pays tribute to the monarch butterfly ( Danaus plexippus ), a symbol of pollinator conservation in North America. This edition aims to raise awareness about habitat restoration and the threats these insects face due to climate change and the loss of their host plant: milkweed ( Asclepias ).

The set includes all six denominations of coins in circulation in Canada: $2, $1, 50¢, 25¢, 10¢, and 5¢ , all with a numismatic specimen finish . It is presented in a book-style case with a removable lens and a numbered certificate of authenticity. The mintage is limited to 30,000 pieces.
The monarch butterfly on the $1 coin
The one-dollar coin , exclusive to this set, features a design by artist Julius Csotonyi, depicting a monarch butterfly in flight against a background of flowering milkweed. The design was sculpted by Alex Tirabasso in detailed bas - relief , with attention to minute details such as the proboscis, antennae, and eyes. The obverse bears the effigy of King Charles III, designed by Steven Rosati.
But what is the Specimen finish?
The Specimen finish is an exclusive numismatic finish that combines a bright or frosted relief with a satin or lined background , elegantly highlighting the design. Unlike circulating coins (standard finish) and proof coins (the highest quality with a mirror polish), specimen coins are produced with greater detail and care, offering a visually appealing intermediate option, ideal for collectors.
