Ichthyosauria, 1 oz. Silver, Mongolia, 500 Togrog, 2017

The Mongolian commemorative coin 500 Tögrög from the "Evolution of Life" series (2017) is a stunning 1 oz silver coin (.999 fine silver) with elegant rose-gold plating. The obverse features the emblem of the Bank of Mongolia and the denomination, while the reverse showcases a highly detailed relief of an ichthyosaur fossil – a marine reptile that lived between 250 and 90 million years ago. Thanks to convergent evolution, it bears a striking resemblance to modern dolphins. The coin utilizes advanced Smartminting© technology, which beautifully highlights intricate details such as the bony ring around the eye and its sharp teeth, giving it an antique finish and high collectible value.

Although the motif is a "fossil," the ichthyosaur on the coin is partially covered with a rose-gold layer, making it look as if it has just been unearthed from the Gobi Desert and still carries the warmth of the ancient sea. With a limited mintage of only 999 pieces, it is especially rare and highly sought after by fans of paleontology and numismatics alike.
