Look again at your code, you only assign a value to coin once, before
you enter the loop.

This is the only assignment.

In general if you are looping for a fixed number of times its easier to
use a for loop:
for tries in range(100):

You ask the user to flip but you never assign a new value
So you need to add an assignment line inside the lop.
The easiest way is just to move the existing line above down
to the start of the loop code.
