Proof gold American Eagle coins will go on sale April 18.
As of press time, prices and mintage ceilings were not available.
Adjustments to the mintages are likely as the 2012 offerings sold just half or less of the coins available, depending on the option.
At $1,600 an ounce, gold is not cheap. The full 4-coin set contains 1.85 ounces of gold.
