The Pentecostal Coin was a mystical item that allowed one to travel to or from Hell. The coin could only be used once. Lucifer was frequently seen spinning the coin as he levitated it. On one side it has the image of Christ on the Cross with the trinity of The Father, The Son and the Holy Spirit. Above this is "In God We Trust". Below is Morning Star. On the other side of the coin is a star with a goat head in the middle. Surrounding this image are the various names of the Devil. Lucifer, Satan, Beelzebub, Dragon and Serpent. Above this is "In God We're Damned". Below is Morning Star.
In "Wingman", Lucifer showed the coin in order to gain access to the auction in order to find his wings.
In "St. Lucifer", it was given to Malcolm by Lucifer in exchange for not shooting him. It was revealed that Lucifer was going to use it in order to return to Hell, but it could also be used by the damned to get out of Hell.
In "Take Me Back to Hell", Malcolm gloats over a dying Lucifer with the coin. Once Lucifer was revived, he punched Malcolm in the face right before Chloe was able to grab a gun and shoot Malcolm in the chest three times. As Malcolm laid on the ground dying and trying to reach for the missing coin that was supposed to be in his pocket, Lucifer revealed that God wanted him back on Earth and returned the coin to Lucifer. Lucifer then flipped the coin in the air to Malcolm and right before Malcolm was able to reach for it, the coin burned up and disintegrated. Lucifer then crouched down and said to Malcolm that he was sorry and that the coin was one use only.
- In ancient Greece mythology, the ferryman of the Underworld, Charon, would only grant passage in return for a gold coin. There are some cultures that bury the dead with gold coins over the deceased eyes because of this.
