Whitman's expanded version of the best-selling Guide Book of
United States Coins (known within the hobby as the "Red
Book") is now available in a fully updated sixth edition. The
384-page volume, called the Professional Edition, is intended for
intermediate and advanced collectors, numismatic researchers,
professional coin dealers, auctioneers, and investors. At 8.5 X 11
inches in size, the Professional Edition is 45% larger than the
regular-edition Red Book. Its combination of more photographs, detailed
higher-grad valuations, listings of additional varieties and rare early
Proof coins, certified-coin population date, auction records, and other
resources provides a wealth of information on every coin type ever made
by the U.S. Mint.
