# Card Dusting

Card dusting enables the player to convert unwanted cards into Koku. The amount of Koku gained depends on the type of card and the borders it has. Players can only convert metal-bordered or rarer cards, and can only convert cards that they own.

The rate of dusting conversion is as follows:

**Common Cards:** 

Metal: 100 Koku 

Gold: 500 Koku 

Light: 1000 Koku

**Champion NFTs:** 

Metal: 200 Koku 

Gold: 1000 Koku 

Light: 5000 Koku
