Originally posted by shooz Considering that coinage is the only money the government can "make", interest free, it's not such a far fetched idea.
The question to me would become how do you keep the commodities markets from trying to corner whatever metal it's coined in.
They sure have cornered the debt market.
That is not what seigniorage is about. Seigniorage is when the government turns a profit (of sorts) on a currency instrument by giving it a face value higher than the cost of production and that piece of currency is taken out of circulation.
For example a US Quarter costs about $.05 to produce (cost of materials, minting costs, QC, etc.) but has a $.25 face value. If the coin goes into circulation and is used it will eventually come out of circulation be recollected, destroyed, and a new quarter will be issued to replace it. If you collected the 50 state quarters and put them in your drawer, the government turns a $10 "profit" (revenue from seiniorage) from your collection of coins.
What MMT is trying to say is that the treasury can force the federal reserve to be a coin collector by producing a coin with a face value so ridiculously high that it will never leave their vault. The coin could be made from $50 worth of platinum or any kind of metal and be given any face value.
The congress usually authorizes these special programs like the state quarters or commemorative coins. I don't know if it requires an act of congress to authorize this or if that is just a courtesy but if it is required I think that would see the same hurdle as you have with raising the debt ceiling. If it is not required then they might as well go for a $5 Trillion coin because they will only be able to pull this trick off once.
