The Official Blue Book®: A Handbook of United States Coins, 2027

Wondering what your U.S. coins are worth?

The 2027 Official Blue Book is designed to help you find out. Now in its 84th edition, this easy-to-use guide shows the prices coin dealers typically pay for thousands of United States coins.

Unlike a catalogue showing what a dealer might charge you for a coin, the Blue Book focuses on the other side of the transaction – what a dealer may pay when buying coins. This makes it particularly useful if you have inherited a collection, found some old coins or simply want a better idea of what your collection may be worth.

You don't need to be an experienced coin collector to use it. Coins are organized by type and date, with photographs, basic specifications and price charts to help you identify what you have and understand its approximate value. The book also explains coin grading – the system used to describe a coin's condition, which can have a major impact on its value.

The 2027 edition contains more than 10,000 listings, with updated market values based on industry-standard Greysheet wholesale pricing. It covers U.S. coins from early colonial issues through today's circulating and collector coins.

You'll also find information on commemorative coins, Proof and Mint sets, and modern bullion coins made from silver, gold, platinum and palladium.

Whether you're sorting through a few old coins, researching an inherited collection, preparing to sell or building a collection of your own, the Blue Book provides a straightforward starting point for understanding what you have – and what a coin dealer might pay for it.
