Seen on eBay
This was seen on eBay in Feb 2016... what the heck IS this ??
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.
Here are some NJ "plates" seen on eBay in early 2020 with the "pick your own numbering and we'll print them out for you" deal.
I like the one with the dog on the couch. "Allow your creativity to flow" caption.
