A set of silver coins with hidden gold in ten of them.

Presenting the latest series of collectible coins from New Zealand Mint. The UFC is the world's largest mixed martial arts organization, bringing together top fighters from around the globe. Fights in the UFC take place in an octagonal cage, and fighters compete in various weight classes, combining techniques from different disciplines such as boxing, wrestling, jiu-jitsu and kickboxing. The UFC has gained immense popularity for its spectacular fights, and its most famous fighters, such as Conor McGregor and Khabib Nurmagomedov, have become icons of the sport. This time, a series of silver coins has been dedicated to the sport's top fighters.

In random 10 sets, one of the silver bars has been replaced by a 1/4 ounce .999 gold bar.
