The swamp outpost Turfary B has a NPC that will convert any of your 'valuables' to AWD at the face value of the valuable.
(also see
Getting Obligatory Bills and cashing in Obligatory Bills for AWD).
The NPC considers a 'valuable' to be anything with a value tag
Examples of valuables are:
- Reality Investment Certificates (value 100 AWD each)
- Scout Cheques (value 20 AWD each)
- Obligatory Bills (value on the bill)
- Anything else in the future where the Value tag appears when you right click
