Small coins or medals made of aurodium mined from Varl, Ardos disks are valuable not merely for their rare metal content, but for what they represent.

ARDOS DISK[1][]
Upon displaying an Ardos disk, a character adds two boost dice to any Charm or Negotiation skill checks made with Hutts or their henchmen or servants. In general, most Hutts will honor the implicit significance of the Ardos disk and refrain from overtly harming or hindering the bearer. If the disk bears the sigil of a rival clan, however, the GM can upgrade the difficulty of any Charm or Negotiation skill checks with the Hutt in question once instead, though the Hutt will still be loath to openly harm the bearer.
