The farther I moved down the taxonomy levels it becomes harder because at the top the classifications in the domain or kingdom are very broad.

Assume that after each shaking, a silver dollar has an equal chance of "head" or "tail" up.
There will be likely 100/2 = 50 dollar coins with "heads" up. Removing them leaves 50 coins.
Again after the second shakes, 50/2 = 25 coins will likely be "heads" up. Removing them leaves 25 coins.
After the third shakes, approximately 25/2 = 12.5 coins will be "heads" up. Of course there is no 0.5 coin. Rounding up you likely get to keep 13 dollar coins.
