1. Counting it down

When the U.S. Mint releases its 2015-W American Liberty, High Relief $100 gold coin at noon ET Thursday, it will be the first-ever U.S. gold coin of that denomination made available. But don't expect it to be available for long.

The most recent highly anticipated Mint release was the Harry Truman Coin and Chronicles Set featuring a Reverse Proof Presidential dollar coin, which sold out in 15 minutes on June 30. It will be interesting to see how long the American Liberty sticks around.
