"Ladies and Gentleman, Children of all ages! Welcome to my Carnival! You will see sights to behold, and things beyond belief! Some may frighten you, and some may shock you, but its all in good fun! Please, stay a while…and watch."
Finally got the idea for an orcish currency:
A cold-hammered piece of raw iron, resembling some kind of a dagger. The Dagger is easy to carry, hard to forge, may be used as a crude weapon in case of emergency AND the iron being a valuable resource... may be used directly for weapon-making. May be carried openly on the belt of a mighty Orc. A new insult: 'to beat someone with someones money' . Self-explanatory.
