The top-left corner of the shop screen displays the credits that will be given to the player in exchange for each of the types of ore that exist in the game. Selling a unit of ore reduces the value of that ore while increasing the value of all other ores. This will hopefully motivate players to venture further out in search of rarer ores.
A player who repeatedly mines the asteroids near the shop may notice that the value of gold ore increases like the jackpot of a lottery while iron ore is ever cheapened.
