This is pure genius.
Congress has provided the authority, in legislation passed during the 1990s, for the US Mint to create platinum proof coins with arbitrary fiat face value having no relationship to the value of the platinum used in these coins. The US code also provides for the Treasury periodically sweeping the Mint's account at the Federal Reserve Bank for profits earned from coin seigniorage generally. These profits are then booked as miscellaneous receipts (revenue) to the Treasury and go into the TGA, closing the revenue gap between spending and tax revenues. Platinum coins with huge face values e.g. $2 Trillion, would close the revenue gap entirely, and technically end deficit spending, while still retaining the gap between tax revenues and spending. If used routinely to close the revenue gap, such jumbo coin seigniorage would reduce the national debt to zero, and remove it as an issue in US politics.
