New Jersey Fake License Plate Governor

The seller described it like this:
This is a strange plate because the front is made of some sort of composition over steel metal.
A magnet sticks to the back of it. From the side there are two metal plates cast into it.
You can see the front corner has a chip. It is a hard substance of some sort.
