The images on the coin are raised higher than the outer edge of the coin. These images stick out so much that you cannot stack these coins on top of each other without having the stack wobble. Therefore, you cannot stack them very high. The images of these coins are more three dimensional than images on regular coins.
When you stack non high relief coins on top of each other, their outer edges contact each other making the stack stable.
