Description
The Extragalactic 2025 5oz Silver Patinaed Coloured Coin is a breathtaking tribute to the mysteries and beauty of deep space.
Extragalactic astronomy explores objects beyond the Milky Way, and few captivate the imagination like the Whirlpool Galaxy (Messier 51). Situated 31 million light-years away in the constellation Canes Venatici, this face-on spiral galaxy reveals its majestic structure of star-filled arms and dense clouds of gas and dust, where clusters of new stars are born. Both a spectacle of cosmic wonder and a crucial site of scientific study, the Whirlpool Galaxy embodies the power and brilliance of the universe.
The coin’s reverse features a vivid, coloured representation of the Whirlpool Galaxy, encircled by inscriptions denoting its name, diameter (23.58 KPC), distance (31 MLY), and celestial coordinates (RA 13h 29m 53s | Dec +47° 11’ 43”). Enhancing the design, four hand-set diamonds — in pink, golden, and white — shimmer like stars in the Galaxy’s radiant arms. Additional details include the designer’s initials ‘NM’, the Perth Mint’s ‘P’ mintmark, and the 2025 year-date.
Each coin is individually patinaed, a process that lends it a distinctive surface finish reminiscent of timeless artifacts, ensuring that no two coins are exactly alike.
Magnificent in size, artistry, and detail, this 5oz silver masterpiece is a rare celebration of the universe beyond our own galaxy — a collectible as unique as the stars themselves.
