Answer

At maximum height, the velocity is zero and the acceleration is $g$.

Work Step by Step

At maximum height, the velocity is zero. Since there is no air resistance when the velocity is zero, the only force acting on the coin is the gravitational force. Therefore, the acceleration of the coin is $g$. At maximum height, the velocity is zero and the acceleration is $g$.
