What was Spartan currency called?

Excuse me, could you please enlighten me on the subject of Spartan currency? I've been reading up on ancient Greek civilizations and I'm particularly intrigued by the monetary system employed by the Spartans. I understand that they were a unique society with their own distinct customs and traditions, so I'm wondering what was the specific name given to their currency? It would be greatly appreciated if you could provide me with this information.
