Lucky Coin

The Lucky Coin is an extremely rare Hardmode accessory that causes enemies to drop extra coins when equipped. The Lucky Coin is dropped by Pirates during a Pirate Invasion at a rate of 1/4000 (0.025%), but is not dropped by Parrots.

With the Lucky Coin equipped, there is a 1/5 (20%) chance that 1 to 10 extra coins will drop each time the player damages an enemy. Each time extra coins drop, the following probabilities determine the coin type:


 * 89.1% chance for copper coins
 * 9.9% chance for silver coins
 * 1% chance for gold coins

Tips

 * Use the Slime Staff and Tiki Armor. Against stronger enemies (like Mimics), the baby slime summoned by the staff will attack rapidly, but only do 1 damage per hit. This offers more chances for coins to drop. Using this tactic during a Pirate Invasion can easily produce platinum coins per invasion.
 * The efficiency of the combination Slime Staff and Lucky Coin is drastically reduced in 1.3 due to the extension of the immune time for enemies. Slime summoned by slime staff can achieve 6 hit per second in 1.2.4.1, but only 3 hits per second in 1.3.0.1 or later versions.
 * Fight weaker bosses like the Wall of Flesh as they will not deal much damage but have lots of health.
