Imagine you had a valid Bounty Hunter License lying around, from a formerly alive friend, (possibly helmet wearing) and somebody would want to buy it from you (possibly along with the helmet)...how much would you want for that?
I know there are people with a much bigger library on this forum, maybe somebody knows more than me and is willing to share his knowledge. I'm thinking very expensive, middle class starship area.
As I see it, an official bounty hunter license doesn't magically open all the doors for you, but especially in the Outer Rim area it might help you get around when dealing with the law for example.
