The 500 ₸ silver proof coin, weighing 31.10 g, is dedicated to Olga’s flax, a rare flowering plant native to southern Kazakhstan. This species is associated with the nature of the Talas Alatau, the territory of the Aksu-Zhabagly Nature Reserve, and the Kishi-Kaindy tract. In folk legends, flax flowers were often believed to possess special, almost magical properties, which enhanced their symbolic significance. The coin’s design features the plant’s inflorescence, conveying its elegance and natural beauty. One of the flowers is highlighted using holographic technology, making the composition especially vivid and memorable. Struck in .925 silver, the coin continues the theme of Kazakhstan’s flora and draws attention to the country’s unique plant species.
