2026 Solomon Islands World’s Purest Bullion II – Kangaroo 1/100 oz Gold Proof Bar
The World’s Purest Bullion Collection II brings the majesty of Australia’s most iconic motif to life with the 2026 Solomon Islands Kangaroo. Struck from 1/100 oz of ultra-pure .99999 fine gold, this exclusive proof bar combines one of the world’s most recognizable bullion designs with the rarest gold purity available today.
The Kangaroo, a timeless emblem of vitality and resilience, is beautifully rendered in proof quality and enhanced with innovative diamond sparkle technology. This process captures and reflects light across every detail of the design, creating an extraordinary brilliance that elevates the artistry of the motif. On the obverse, the effigy of His Majesty King Charles III affirms its sovereign status, while the reverse highlights the striking Kangaroo in radiant detail.
Issued in 2026 and backed by the Solomon Islands, each gold proof bar carries a legal tender face value of 10 Dollars. Compact yet powerful in presence, its 15 x 8.5 mm dimensions make it an exceptional piece for both display and secure storage, appealing to seasoned investors as well as discerning collectors.
With a worldwide mintage limited to only 10,000 pieces, the Kangaroo is a rare treasure within this twelve-part collection. Its scarcity, combined with its ultra-pure composition and dazzling finish, ensures long-term desirability as both a collectible masterpiece and a sound investment in gold.
