Gerry Fortin’s definitive Web-based book on Liberty Seated Dimes from 1837 to 1891 features an easy-to-navigate table of contents that quickly takes collectors through the major design groups, varieties, and dates for these collectible coins. Six helpful indexes cover everything from double-die instances to other minting errors, and new variety discoveries are continually being added. Photos of a coin’s obverse and reverse, as well as details when required for clarity, accompany all Seated Dime descriptions.
