Bring on the mint to strike a few new coins.
“The Congress shall have power...To coin money, regulate the value thereof,....”
Unless the Congress explicitly sets the value of a coin, it has no domestic legal value in my opinion.
A platinum Biden coin with One Trillion Dollars on it will have the market value people will pay for such a thing.
Can’t wait to buy them on The Coin Vault or whatever the stupid home shopping channel is - I saw it on TV over the weekend with dollar coins or something - maybe half-dollar
