In Washington, the U.S. Mint unveiled the complete collection of the inaugural year's "First Spouse Coin Collection."
This is the first U.S. coin series that honors only women.
The latest in the gold-coin line, "The Dolley Madison," goes on sale Nov. 19.
First Lady Laura Bush was on hand to help introduce the new coin and the completed 2007 collection.
"Their appeal reflects the enthusiasm of America's coin collectors, the public's fascination with American history and Americans' interest in our remarkable first ladies," Mrs. Bush said.
The gold coins are minted in denominations of $10, but they're worth more because they're a half-ounce of 24-karat gold.
Coins released this year picture Martha Washington, Abigail Adams and Dolley Madison.
