Lucky Coin

The Lucky Coin is an extremely rare Hardmode accessory that while equipped causes enemies to drop extra coins when damaged. The Lucky Coin is dropped by Pirates during a Pirate Invasion at a rate of 1/4000 (0.025%) or from the Flying Dutchman at a rate of 1/200 (0.5%), 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

 * The Lucky Coin is very rare. It could take 33-34 complete Pirate Invasions before it drops.
 * Farming Lucky Coin/Discount Card/Coin Ring is most efficient from Flying Dutchman, rather than from common pirates. After getting event progress to 50%, you can ensure 10 Flying Dutchmen per event by getting high enough above ground (using small platform or flying mount), but not too high, so that spawned enemies will be in "Active Rectangle" and will despawn after 12.5 seconds, and then spawn again. Until Flying Dutchman eventually (usually it takes a short time) will spawn. After killing him, repeat the process till event ends. Parrots could reach you this way too, but you can kill them safely, they do not count towards event progress.
 * This item is generally considered to be the best way to make money in-game, when paired with a very weak weapon, usually a Slime Staff with the Broken Modifier.
 * To maximize profits, use the Slime Staff and Tiki armor together. Against stronger enemies (like Mimics), the baby slime summoned by the staff will attack rapidly, but only do 1 damage per hit. And with the Tiki Armor, you can summon even more baby slimes to hasten the process. This offers more chances for coins to drop. Using this tactic during a Pirate Invasion can easily produce platinum coins per invasion, and during a Solar Eclipse to produce  platinum coins per eclipse.
 * After defeating the Golem, his chamber in the Jungle Temple is also a good place to farm a steady stream of weak enemies, with the occasional Mimic adding to the haul.
 * In Expert mode, enemies have increased health which means the amount of platinum coins can skyrocket anywhere from . Enemies also pick up coins in expert mode, however, so letting anything escape can reduce the amount gathered dramatically.
 * Fight weaker bosses such as the Wall of Flesh, as they will not deal much damage but have lots of health.
 * Try using a Minishark. Its damage is low enough that it will usually only do one damage per hit to stronger enemies. Paired with its fire rate, the amount of coin drops increase drastically. To further decrease damage (and therefore increase how many hits you can achieve), consider a modifier that decreases damage. Frenzying can be a good choice, as it both decreases damage and increases speed.
 * A Chain Gun can be good for maximizing hits against enemies that are too strong to approach with a Minishark.

Trivia

 * As with the Lucky Horseshoe, it is possible to receive the Lucky modifier, giving it the name Lucky Lucky Coin.
