Default Re: classical physics - rod anchored to ground, rotational inertia
For the moment of inertia one... the moment of inertia of an off-axis penny is the penny's moment of inertia around its own center, plus the moment of inertia of a point mass at that distance from the central axis.

So, final answer will be 7*MI of penny around its own axis + 6*MI of point mass one penny-diameter from the axis of rotation.
