# An Ancient Greek Golden Drachma with Athena’s Symbol, the Owl.

Golden drachmas are large, round coins that are usually made of gold or silver. They were used as currency by the Ancient Greeks. Mortals used to use the silver drachmas. However, as Chiron stated in The Lightning Thief, the gods never use anything less than pure gold. They are described as big as Girl Scout cookies by Percy, and are used by the gods and demigods. The drachmas have images of various gods stamped on one side, and the Empire State Building on the other.


The ancient mortal drachmas were made of silver, but the gods now do not use anything less than pure gold mined from Olympus. Golden drachmas are used as currency, to send Iris message, and for getting a taxi ride from the Gray Sisters.

# An Ancient Greek Drachma.

Drachma can be used for the following:

  • To create an Iris Message
  • As payment to get into the Underworld
  • To pay the Gray Sisters to take you anywhere as long as its within their serving area
  • As payment for sending a letter or package along the Hermes Express

Currently, the pure gold drachma is the main currency of the gods, goddesses, and demigods.

The most common use for the drachma is to send an Iris Message through Iris, the rainbow goddess. It is used for contact when nothing else is available, and is quite useful if any extra drachmas are allowed for use.

The Lightning Thief

After beheading Medusa, Percy Jackson fills a pouch with drachmas and mails the head to Olympus. He later uses some drachmas to bribe Charon when he first enters the Underworld.

The Sea of Monsters

When summoning the Gray Sisters' Taxi, Annabeth Chase throws a drachma in the street which falls through.

Hermes includes a bag of golden drachmas in the duffle bags that he gives to Percy for Percy, Annabeth and Tyson to use on their quest.

While searching for money, Percy discovers that all he has on him is a single drachma. Later, he uses the drachma to create an Iris Message to Camp Half-Blood so that he can trick Luke Castellan into revealing to everyone that it was he who had poisoned Thalia's Pine Tree.

The Titan's Curse

Poseidon adds a saltwater fountain to his cabin filled with golden drachmas, presumably to make Iris messaging easier for Percy. Percy subsequently uses this to communicate with his half-brother Tyson and his mother Sally Jackson.

Percy later uses a drachma to send an Iris Message to Dionysus.

The Battle of the Labyrinth

Percy receives a collect Iris Message from the spirit of Bianca di Angelo in the Underworld which requires him to throw a drachma into the message himself.

The Heroes of Olympus

The Son of Neptune

Roman demigods don't use drachmas because it's Greek currency. Instead they use denarii. The Romans never used Iris Messages like the Greeks because they relied more on their giant eagles and road systems.

The Mark of Athena

The first Mark of Athena takes the form of a silver drachma given by Athena and Minerva to her children.

It's mentioned that while Percy was missing, Annabeth had spent hundreds of golden drachmas on Iris-messages to every friendly spirit, demigod or monster that they had ever met in search of him without any luck.

The House of Hades

Frank Zhang notices that Coach Hedge's nightstand contains a bottle of water, a stack of golden drachmas, a flashlight and a glass prism for making rainbows, causing Frank to realize that the coach had come prepared to send a lot of Iris-messages.


The Lightning Thief

Percy, Grover Underwood, and Annabeth find a fountain filled with drachmas at Aunty Em's Gnome Emporium which they later use to pay Charon after their mortal money was burnt by him.
