The most common coin that adventurers use is the gold piece (gp). A skilled (but not exceptional) artisan can earn a gold piece a day. The gold piece is the standard unit of measure for wealth.
The most prevalent coin among commoners is the silver piece (sp). A gold piece is worth 10 silver pieces.
Each silver piece is worth 10 copper pieces (cp).
Merchants also recognize platinum pieces (pp), which are each worth 10 gp.
The standard coin weighs about a third of an ounce (fifty to the pound).
In general, something can be sold for half its listed price.
Commodities are the exception to the half-price rule. A commodity, in this sense, is a valuable good that can be easily exchanged almost as if it were cash itself. Wheat, flour, cloth, and valuable metals are commodities, and merchants often trade in them directly without using currency. Obviously, merchants can sell these goods for slightly more than they pay for them, but the difference is small enough that you don't have to worry about it.
