The coin functions perfectly well. The thing I don't like is that its shinier than a piece of tin
foil. At night or under subdued lighting this is less of an issue, but in broad daylight or under
bright lights this thing is going to look exactly like what it is - a fake. You get what you pay
for. If realistic appearance isn't an issue for you, by all means buy it. Like I said, it works
just fine for its intended purpose. Your call.
