Coefficient of static friction is greater.

the value of coefficient of static friction and coefficient of dynamic friction depends upon nature of surface but usually coefficient of static friction is greater then coefficient of dynamic friction. coefficient of static friction values generally range 4m 0.01 for smooth surface to 1.5 for rough surface

Static is higher. You notice this when you are pushing a car that has stalled. It is harder to get the car moving (static) than it is to keep the car rolling (kinetic).
