Coins serve as the currency for shops, the payment for the Donation Machine in shops, and payment for the slot machines, fortune telling machines, shell game, beggars, and Restock Boxes. They are also consumed to use a few activated items (most notably Magic Fingers and Portable Slot).

Notes

• Humbling Bundle does not double Lucky Pennies, making them very easy to spot.
• Bumbo and Bum Friend are unable to pick up Sticky Nickels; they instead hover over them attempting to pick them up.
• Unlocking Sticky Nickels doesn't reduce the spawn rate of regular Nickels; rather, Pennies have an additional chance to become Sticky Nickels.
• Booster Pack #5 added a green glow to Lucky Pennies, making them easier to spot. This was from this Steam Workshop mod by piber20.

Unlockable Achievements
