Coin Crown

 is a passive item in both Enter and Exit the Gungeon.

Effects

 * Adds a chance to gain money upon clearing a room.
 * If Coin Crown triggers, it will spawn a 5 shell on top of the player.

Trivia

 * This could be a reference to Crypt of the Necrodancer's Crown of Greed.
 * The "Two Heavy" synergy is a nod to the old adage, "Heavy is the head that wears the crown," as in this case, you would be wearing two.
