After being sufficiently annoyed by the ship tokens getting mixed up and me having to look through every last one to find the one I needed, I made an organizer for the tokens.
A piece of plasticard cut slightly bigger than the token and two lengths of plastirod (one fitting inside the other) netted me this system;
Glue the rods together slightly off-set.
Glue the rods to the plasticard.
Drill or cut a hole in the plasticard from the back.
