We try to make sure vestigial resources/items can be sold for credits at least. If you have one collecting dust that cannot be sold, let me know, and I'll see what we can do.

Not a resource but how about the captura scenes we're flooded with from Jupiter and SO/ESO? I would gladly dump those for 500 credits each or some ducats.

I'm adding a sell prices for those. Thanks for letting me know.
