The Crostini Medallion is a valuable and supposedly cursed piece of jewelry from Transylvania.
It is round with a circle of small green stones in the center, and it is inscribed with the words, "Serip mav emoc lew" which is "Welcome vampires" backwards, with both words having each syllable seperated.
According to Transylvanian art expert Lugo Belasi, whoever held the medallion and read the inscription would be haunted by a vampire. He told Shaggy Rogers this after he had already read the inscription aloud. Soon, a vampire showed up and stole the medallion.
