Baum bag

Baum (バウム) is the actual currency of the planets Aries and Janbarik (Paperock), and probably all nearby planets. The currency comes with a character 'U' crossed by two parallels lines in its middle, looking like the Yen currency actual symbol, which has instead an 'Y'.

Baums are usually found in bags, big or small sized. In Janbarik, baums are also found in coin version.
