The Coin Gun being used to attack Target Dummies. Note the value of the coin increases its respective damage.

The Coin Gun is a Hardmode ranged weapon that uses coins as ammunition, which affects its damage and velocity depending on the type of coin fired. The weapon itself has 0 base damage, with the entirety of its damage value stemming from the coins used to fire it. Coin projectiles dissipate upon hitting an enemy or solid block and cannot be retrieved once fired. The Coin Gun is dropped very rarely ( 0.025*1/4000 (0.025%) / 0.0125*1/8000 (0.0125%) chance) by regular Pirate Invasion enemies, excluding the Parrot. The Coin Gun's drop chance from Pirate Captains is quadrupled ( 0.1*1/1000 (0.1%) / 0.05*1/2000 (0.05%) chance) and increased again from the Flying Dutchman ( 2*1/50 (2%) / 0.25*1/400 (0.25%) chance).

The Coin Gun cannot be reforged, and therefore cannot have modifiers.

The Coin Gun cannot receive any modifiers that increase damage, so the modifier that boosts its DPS the most is Agile (+12% speed[1], +3% critical strike chance). Zealous (+5% critical strike chance) serves as the most ammo-efficient option, dealing the highest amount of damage per coin fired.

  • All ranged damage bonuses from equipment will be applied to the traits of the coins used to fire it (a Destroyer Emblem will add 8% critical strike chance to the Coin Gun and Gold Coins, but will only add the 10% damage bonus to the Gold Coins).
  • The Coin Gun is not affected by the damage bonus of any Shroomite armor helmets, but ammo conservation effects such as that of Shroomite armor, the Ammo Box or the Ammo Reservation Potion works normally.
  • Coins are consumed from the designated coin slots first, then the inventory (from top left to bottom right).
    • Coins are consumed from the inventory first (from top left to bottom right), then the designated coin slots.
  • In Celebrationmk10 worlds, the Coin Gun can be purchased from the Princess for 30 after completing a Pirate Invasion for the first time.


  • If used with Platinum Coins, the Coin Gun is easily one of the most powerful weapons in the game, though this can make combat prohibitively expensive.
  • Combining the Coin Gun with either the Lucky Coin, Coin Ring, or Greedy Ring, can establish a somewhat infinite supply of ammo, as long as combat is intensive.
  • The Coin Gun becomes much more viable in Expert Mode due to the larger volume of coin drops.
  • It pairs well with Vortex armor or Shroomite armor as it greatly increases the DPS and reduces coins used.
  • The Coin Gun firing Platinum Coins has a similar damage output per shot as the Sniper Rifle, but with nearly five times the fire rate.
  • In Journey Mode, the player can duplicate infinite amounts of Gold/Platinum Coins starting with just one Silver Coin, thus making the Coin Gun an extremely powerful weapon for Journey Mode.
  • Without taking defense into account, it is more cost-efficient to convert coins to lower denominations for ammo. However, this comes at the cost of a lower damage rate. Because 1,000,000 Copper Coins can be made from a single Platinum Coin, Copper Coins are 125,000 times more resource-efficient than using platinum to achieve the same damage.
  • The Coin Gun requires a constant craft of 100 low-tier coins because the pickup of coins can convert the stacks with lower than 100 coins into a higher-tier coin, otherwise it can eventually use unwanted coins. It requires constant attention to the ammunition amount indicated. If there is less than 200 ammo, it can start using Silver, Gold or Platinum Coins.
    • The Encumbering Stone can be useful to ensure that extra coins are not picked up accidentally over the course of a battle.


  • The Coin Gun remains an extremely rare item. Before 1.3, it took an average of 66–67 Pirate Invasions to be completed before it dropped. With the addition of the Flying Dutchman in, there is an increased chance for the Coin Gun to be dropped, but it is still very rare.


  • Console 1.03: Built in an auto-destruct for items that the player should never have (the list includes Coin Gun).
  • Console 1.02: Introduced, but not implemented due to a different currency handling in the console versions causing the Coin Gun to randomly shoot coins of any value.


  1. By default, Agile increases speed by 10%. However, like with all modifiers, the effective increase differs from weapon to weapon due to rounding. For the Coin Gun specifically, Agile increases speed by an effective 12%.
