Dumbledore's Army coin
From Harry Potter Wiki
The Dumbledore's Army Coin was a fake Galleon created by Hermione Granger in 1995 to inform members of Dumbledore's Army when the next meeting would take place.
[edit] Creation
Hermione fabricated fake Galleons, on which she then placed a Protean Charm. Around the edge of each coin was a series of numerals which represented a serial number belonging to the Goblin that cast the coin. The Protean Charm allowed these numerals to change into the time and date of the next meeting of the DA whenever the master coin, owned by Harry Potter, was changed. The coin would also warm up to alert the holder to the change.[1] She has got the idea from Voldemort pressing the Dark Mark on the arm of his Death Eaters, summoning them. However, Hermione chose to engrave the date on the coins, rather than on the members' forearm. She also didn't want to steal Tom Riddle's idea because they were partly fighting him and Dolores Umbridge
In 1998, Neville Longbottom used the coins to summon former members of Dumbledore's Army to Hogwarts School of Witchcraft and Wizardry to fight the Death Eaters and reclaim the school. The former members alerted many others, including the Order of the Phoenix, and set the scene for the Battle of Hogwarts.[2]
In later years, the surviving members of Dumbledore's Army would keep their coins, regarding them as badges of honour.[3]
