Answer 1

This one should be available at your local public library or any coin shop:
Guide Book of United States Coins (also known as the Red Book), by R. S. Yeoman
This is the most commonly used US coin reference book. Bear in mind that the prices listed are approximately what a dealer would charge you for a particular coin. The price a dealer would pay will be less.
