Fake Galleons
Chapter 5
- Galleons made of Leprechaun gold were common at Quidditch games where Leprechauns are the mascots for the Irish team. These Galleons are occasionally in temporary circulation (they vanish a few hours after appearing), but goblin experts at Gringotts can differentiate them from real ones.
Rubeus Hagrid used Leprechaun gold in a Care of Magical Creatures class, while teaching students about Nifflers' ability to hunt for shiny objects such as coins.
Ludo Bagman used Leprechaun gold to pay Fred and George after their bet, resulting in them blackmailing Ludo with no luck
Hermione Granger fabricated fake Galleons for the members of Dumbledore's Army as a means of conveying clandestine communication about the time of future meetings. The coins are linked by a Protean Charm, allowing the other coins to mimic the change of one coin.
- Draco Malfoy copied Hermione's idea of using enchanted coins to communicate with the Imperiused Madam Rosmerta during the 1996–1997 school year.
