In what direction does the centripetal force direct to?
(Static) Frictional force would be the centripetal force to cause the coin to undergo circular motion.

Centripetal force is a resultant force NOT a real force, it is a name given to the resultant of all the real forces that cause an object to undergo circular motion.
In this case, the forces that acts on the coin are normal force, weight and frictional force. Only frictional force can act on the coin for it to undergo circular motion.
