The Silver Bit is the standard coin throughout all who deal in currency in Tunwic. A round coin made of silver with a hole punched through the middle so that they may be threaded together. 1 Silver Bit is equal to 10 Copper Drabs or 1/10th of a Gold Noble.
Often times, people will cut a gold Noble in half, referred to as a half-Noble or sometimes a gold Knuckle. This half-coin is generally still accepted and held to be worth about 5 silver Bits. Some merchants refuse these coins however.
