Keep this in mind. This is a zinc coin. So it has less strength when circulation happens from contact with other coins. They get dropped, flattened, worn down, squeezed into rolls and all other kinds of torture. Best way to see what I'm talking about as to size of devices, take another normal coin and take images of the exact locations on the devices and put them top and bottom. Then you will see that they are normal in size. This way you will know for yourself. I want you to be convinced when you see them side by side. The more a person digs in on a subject, the better informed he will be. I'd do that for you, but I don't have my older Photoshop program on my new computer. The new program they want over $2,000+ dollars for it) The other software I have now is a joke. So that is how I would resolve it. See if for yourself.
