Boxing of The Final Empire
A Boxing is the nickname for an imperial gold coin in the Final Empire. The name comes from the picture on its back of Kredik Shaw, the Lord Ruler's palace—or, the 'box' in which he lives.
Boxings can be used by Mistborn and Coinshots for jumping and attacking. Copper Clips are more commonly used for this purpose since they are more common and worth less. The Allomancers throw the coin on the ground and push upon it to fly into the air. Alternatively, they throw the coin at the enemy and push upon it to shoot it into the enemy's body, much like a bullet.
