Okay, jackass. Like I said, the law doesn’t care what your stupid blog says.

“Federal Reserve notes are not redeemable in gold, silver or any other commodity, and receive no backing by anything This has been the case since 1933. The notes have no value for themselves, but for what they will buy. In another sense, because they are legal tender, Federal Reserve notes are “backed” by all the goods and services in the economy.”
Therefore a $1 trillion dollar coin or note can indeed be issued and it is wholly irrelevant of the material used to produce the coin or note.
But don’t let that stop you from putting your pussy hat on and screaming at the sky because Paul Krugman thought platinum would be an appropriate metal for the coin.
Holy crap man you’ve lost it.
“A bullion coin is an investment-grade coin that is valued by its weight and fineness of a specific precious metal. Unlike commemorative or numismatic coins valued by limited mintage, rarity, condition, and age, bullion coins are purchased by investors seeking a simple and tangible means to own and invest in the gold, silver, platinum, and palladium markets.”

“United States Mint bullion coins are sold based on the prevailing market price of gold, silver, platinum, or palladium plus a small premium to cover minting, distribution, and marketing costs.”
You lost. Take a hike!.

Sorry, but you just don't know the law:
31 U.S. Code § 5112 - Denominations, specifications, and design of coins
"(k) The Secretary may mint and issue platinum bullion coins and proof platinum coins in accordance with such specifications, designs, varieties, quantities, denominations, and inscriptions as the Secretary, in the Secretary’s discretion, may prescribe from time to time."
They are only legally authorized to mint platinum bullion or proof coins, and are not authorized to mint legal tender platinum coins. Proof coins would not be depositable in a bank account, and bullion coins would be valued at the current bullion price, regardless of the face value amount printed on the coin.
