[USMA:50973] Why mint coins no one wants?

[John M. Steele]

Per this article on dollar coins, the US has $1.2 billion minted reserve of the 
$1 coins already due to low demand, and by 2016 will have a minted reserve of 
$2 billion of them.
 
At 8.1 g/coin (per the Mint), that is 16200 t of excess coins by 2016.
