Nope, not talking about paper money. This will work in a barbaric-flavored campaign:
Swipe a custom from the Norse, specifically "hacksilver". Jewelry is pre-scored to make it easier to hack off a piece. A merchant weighs the piece and the value of the weight of precious metal is the "money".
Other barbaric forms of "money":
Clan wealth as currency: You don't have cash, but Uncle Sven is known to be a man who has many cattle. So you put it on Uncle Sven's tab. The merchant goes to Uncle Sven to collect later. Uncle Sven has to pay up in goods or lose honor. If you didn't clear it with Uncle Sven, he can have you cast out of the clan. Even if he doesn't go that far, you may owe Uncle Sven a favor or fifty for it.
Status as currency: You're a hero. Your stock in trade is being a hero. Careful about how much of a "reputation tab" you run up. Outlawry can be a hassle. Some barbaric cultures had a class of warriors who could essentially count on home, food, supplies, weapons, etc. simply because they were heroic warriors. However, that also meant that they were "on call" and could not turn down legitimate commands from their war-chiefs.
