Coins

Coins are Terraria's unit of currency. They are primarily used for NPC transactions, though other players may also accept them as payment in multiplayer. Coins can also be used as ammunition for the Coin Gun. There are currently 4 types of Coins: Copper, Silver, Gold, and Platinum.

Coins can be obtained by killing enemies, interacting with NPCs, or finding them in multiple forms of loot. Despite Coins appearing as the materials "Copper", "Silver", "Gold" or "Platinum", they are unrelated to ores and cannot be crafted from them.

The coin value an enemy drops upon death is calculated from fixed values in the game code, with some random variation.

Crafting
Coins can be "crafted" by hand, which combines or splits them into other denominations. Each coin is worth 100 of its lesser denomination (Copper -> Silver -> Gold -> Platinum). When picked up, Coins are automatically combined into their higher denomination, if possible. For example, if the player picks 100 Silver Coins, they'll end up with one Gold Coin in their inventory instead. Similarly, a player holding 96 silver coins picking up another 15 will give them a gold coin and 11 silver coins.

Death penalty
Upon player death in Softcore Mode (the default mode), half of all of the stacks of coins in a player's inventory are dropped, rounded up to the nearest whole coin. For example, if the player possesses 1 Gold Coin in one stack, it will be dropped. If it is instead 10 coins, 5 will be dropped. (Note that 75% of the player's coins will be dropped on an Expert Mode world.)


 * Upon player death in Mediumcore or Hardcore Mode, all coins are dropped, regardless of how the player died.
 * Being killed by a player-wielded weapon will not cause the player to drop any coins in Softcore Mode, even if recently damaged by an enemy.
 * Other forms of suicide that can occur by accident, such as Fall Damage or Chaos State, will cause coins to drop.

Storage
Inside the player's Inventory, Coins have their own special slots, although it is possible to move them into normal inventory slots.
 * Coins stored in the trash slot will not be dropped upon death. This is a good way to store your highest value coins if you feel you are about to die. You can then take it out of the trash slot when you respawn. If you accidentally place something else in the trash, though, the coins will be lost.
 * In the early game, before receiving the piggy bank, it may be inevitable to store your coins in a chest. However, quick stack does not place coins in chests. Deposit all does place coins, but if the chest is already full when you press deposit all, higher denominations may be destroyed if a stack for that coin doesn't exist.
