ZODIAC SIGNS - KAZAKHSTAN
The National Bank of Kazakhstan holds an international patent along with exclusive rights to produce tantalum coins. The 'Zodiac Signs' series magnificently showcases the distinctive characteristics of this rare-earth metal. Each coin is designed as an octagon, featuring patterns reminiscent of ancient cave art. The colors of the tantalum inserts reflect the four main elements: earth, water, fire, and air. Uniquely, all coins in the 'Zodiac Signs' series were issued together within the same year, setting them apart from other collectible coins.
