Coins

Coins are Terraria's unit of currency. They are usually used for NPC transactions, but some players also accept them as payment in multiplayer.

There are four types of coins in Terraria: Copper Coins, Silver Coins, Gold Coins and Platinum Coins. Each is worth 100 of the previous one, and thus one Platinum Coin is worth a million Copper Coins.

Coins can be stored in a Chest or Piggy Bank, like other items, which will prevent them from being dropped upon death, as the death penalty is dropping half your carried coins (rounded up).

Coins have their own special set of 4 slots to the right of the inventory.

An easy way to make coin is to harvest sand with bombs found in pots, then convert the sand into glass and then into bottles. This technique makes deserts virtual gold mines.
