This stunning second release in the Australian Opal Wings series captures the beauty of the native Blue Triangle butterfly (Graphium sarpedon choredon). Struck in 1oz of 99.9% pure silver to proof quality, the reverse showcases the butterfly in exquisite detail, resting among hibiscus blooms, with a genuine opal insert set into the wing that flashes with vibrant colour. The luminous opal adds a distinctly Australian touch, creating a striking contrast against the frosted and mirrored surfaces of the coin.

The obverse features the official portrait of King Charles III, while the coin is presented in a deluxe wood-effect display case with a matching outer box. Limited to just 1,000 pieces worldwide and issued as $2 legal tender of Niue, this elegant proof is a standout addition for collectors of Australian wildlife, opal-themed issues and premium silver coins.
