http://moneyland.time.com/2011/06/29/inside-the-fed’s-vault-1-billion-worth-of-unused-coins/ In the basement of a Baltimore vault the size of a soccer field, 1 billion dollar coins are just sitting there. Thanks, Congress.
Its hardly Congress' fault if Americans are too stubborn to use a superior type of low-denomination currency.
Melt value would exceed the value of a $1 fiat fed reserve note so if I was in the US I'd definitely take them over paper.
Also worth noting: Check my maths, but if only 60% of them made it into circulation, the US Mint would have made 2.5 billion $1 coins in total. 2.5 billion * 30c = $750 million to produce. Cost = $750 million Sales = $1.5 billion (2.5 billion minus 1 billion in the vault leaves 1.5 billion that must have been sold). Profit so far = $750 million So even with a billion dollars sitting unsold in the vault, the US government has made three quarters of a billion dollars on an "unsuccessful" program. I wish I could screw up like that.
