Coins are pickups that serve as the main currency for Shops, Machines and beggars. Notably, both Keeper and Tainted Keeper use coins instead of hearts to refill their health.

Fiend Folio adds 6 brand new coins that provide additional effects when picked up.

This page is about Coins added in Fiend Folio. More information about Coins in general can be found in the vanilla page.

Notes

• Cursed Pennies have an independent 1% chance to become a Golden Cursed Penny; in effect, any random coin drop has a 0.0067% chance to become a Golden Cursed Penny.
• Coins dropped from opening chests or Grab Bags have a 1% chance to become a Token. Other coin drops can not become Tokens.
• Fiend and Tainted Fiend both have a hidden increased chance for coin drops to become Cursed Pennies, being at an approximately 5% chance by default.
• The Lost and Tainted Lost both have double the chance for coin drops to become Haunted Pennies, being at an approximately 1% chance by default.
• Picking up Cursed Pennies and not gaining any coins will not heal Keeper or Tainted Keeper if they are missing health. However, they will also not have any health subtracted if coins are lost.
• Various penny-related trinkets have unique interactions with Fiend Folio's Cursed Pennies. Chance-based effects will scale with the value and quality of the Cursed Penny:
  • Bloody Penny will have a chance to drop a 1/3 Morbid Heart.
  • Burnt Penny will have a chance to drop a Copper Bomb.
  • Flat Penny will have a chance to drop a Spicy Key.
  • Blessed Penny will have a chance to drop a Half Immoral Heart.
  • Cursed Penny (Trinket) will have a 12/13 chance for Cursed Pennies to teleport to another location in the room when attempting to pick them up. Successfully collecting a Cursed Penny will teleport the player as usual.
    • The Black Candle will completely negate this interaction.
• Guppy's Eye shows which pickup a Token will mimic.
• Tokens cannot be duplicated with Jera.

Trivia

• Golden Cursed Penny appears to be colored rose gold as opposed to actual gold.
• Stud appears as a Part 4073, a common building piece also found in Lego sets which is nicknamed the "stud".
  • The Stud's existence as a coin variant is a reference to the usage of the Lego part in Lego Video Games as currency. Picking up the Stud even makes the same sound as Studs from said games ― specifically, the sounds made by purple Studs.
  • Its effect of damaging monsters and Isaac is a reference to the common cliché of Lego pieces being extremely painful to step on.
• Lego Stud was added in V2.5.
• Tokens were added in The Spitshine Update.
• Token's appearance resembles Wild Card, a card that mimics the effects of other consumables/items.
