You can now own a $1 gold coin celebrating one of America’s most revolutionary achievements: the NASA Space Shuttle program.

The mint set noon EDT on Thursday (May 15) as its T-0 for the launch of Florida's dollar celebrating the retired spacecraft.

A good place to start is to buy a copy of “A Guide Book of United States Coins,” also known as the Red Book. Learning about coin values will help you avoid bidding too high at auctions.
