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.

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

Obtaining Coins
Coins can be acquired by killing monsters, breaking pots, or trading with NPCs (or other players). Even though the Coins are "Copper", "Silver" or "Gold", it is impossible to craft them from Ore, Bars, or any other item in general (apart from a different rank of Coins).

Coin Harvest Technique
An easy way to acquire Coins is to harvest Sand Blocks, craft the sand into Glass then Bottles, and then sell those to an NPC for about 20 Silver per 99. This works well because sand is especially easy to harvest. This technique makes Deserts a virtual Coin mine.

An even better way, however needing a few items such as a Bucket and a Nightmare Pickaxe, is to use an Obsidian Generator to mass-produce Obsidian Skulls. These sell for 54 silver each, so selling two of them already give you over 1 gold coin. With this technique, it is possible to acquire the Minishark in half an hour.

Obtaining coins through battling Meteor Heads is also an easy option, but it requires 50 Meteorite and preferably something good to beat Meteor Heads with. (Bases guide on farming Meteor heads)

See Guide:Selling Items for more information on acquiring coins.

Storage
Like other items, Coins can be stored in Chests and Piggy Banks. It is recommended to always store them, as it will prevent them from being dropped upon death, the penalty of which is dropping half of your carried coins (rounded up).

Inside the inventory, Coins have their own special set of 4 slots on the right of the inventory grid.

If for some reason, you cannot store your coins, and are carrying a single high value coin (a Gold Coin early, or a Platinum Coin later), then it might be a smart move to "break" the coin: If you were to die, you would lose only half of the low currency Coins, as opposed to the entire high currency Coin. it is also possible to put the coins at your cursor so you can keep them when you die.

Crafting
Coins can be crafted By Hand. Each coin is worth 100 of the sub denomination. A point of interest to note is that when the player picks up an item, the coins are automatically crafted if possible. This means that if the player picks up hundreds of Silver Coins, he'll end up with a few Gold Coins in his inventory, and less than 100 Silver Coins. This means that you can craft coins a lot easier (especially if you are up against a wall) by simply throwing a stack of coins out of your inventory. When you pick them up, they will be crafted for you. So if you threw 100 silver coins out of your inventory, you would pick up 1 gold instead.
