Coins are the basic form of currency in the Binding of Isaac. They can be gathered in the form of Pennies, Nickels, Dimes (Wrath of the Lamb only), the Quarter or the all-coveted Dollar. You can hold a maximum of 99 cents at any time, any additional coins collected beyond this point will do nothing. Coins can be used to purchase items from the Shop. Beyond that, coins can also be used in gambling at the Arcade with Slot Machines or with Shell Games. Additionally, coins can be donated to Beggars for pickups and a free item. Coins can also be used with the Portable Slot item. Lastly, coins can be used to gain a damage boost from the Money Equals Power passive item.
