Crafted from pure gold, the present coin is&nb✃sp;a collaborative effort of Swiss artist Hans Erni and the master watchmakers at Piaget. Born in 1909, Hans Erni is not only famous for his surrealist and experimental art style, but also well known for his mastery🅷 on miniature illustration such as stamps and coins. Displaying a pigeon and an hourglass in front, the back reveals two faces which could be viewed both ways, making the present coin a true showcase of Hans Erni's master craftmanship and wild imaginations.
