|This item really only makes sense in Multiplayer. You could craft it alone if you really wanted to, but what would be the point of that?|
OR you use our patented crafting-window-to-galactical-bank-teleportation system and trade/craft 9 coins back into a single refined iron ingot.
Yes, this is costly and ill-advised, but it's not our bad for the galactical bank setting that sort of price.
Plain iron or even uu-matter is otherwise used as currency on servers.
