Sack of Pennies is an item. It is a brown bag with the cent mark on its front.
Isaac is followed by a small bag that drops a coin upon completion of every two rooms. Usually a Penny, sometimes a Nickel, and rarely, even a Dime.
Money Equals Power - Allows Isaac to increase damage much more quickly.
- If Isaac already have Little Steve, Robobaby, or Sister Maggy with Isaac when Isaac pick this up, he will bug out and turn into Brother Bobby until Isaacu leave the room. If Isaac already have Sack of Pennies and pick up Little C.H.A.D. the Sack of Pennies will turn into Little C.H.A.D. but still have both effect.
