I also would like to set up a bounty to do some touch up on the JKC icon. Something along the lines of adding some blue around the boat ('Junk') and perhaps some silver inlay in the gold portion. The mono-color gold just does not stand out, but I like the basic design of the coin icon.
I think that there is no need for boat in coin icon, boat can be on site in header with short explanation beside what is Junk ship, coin must be striking and simple, I have some ideas. I'll try to make something different than other coins.
