As for what it is, it is a "Chinese fantasy dollar". The Chinese have been making fake base-metal replicas of world silver crowns and dollars for decades, as well as numerous fantasy "bullion coins" that aren't actually made of silver.
So yes, pretty much everything stated on or implied by this "coin" is a lie. It's not a coin, it's not 1 troy ounce, it's not .999 silver (it is not silver at all), and it wasn't made in America.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
