After collecting and researching the Seated Dime series for over twenty years, I'm happy to present the 3rd reference book to the numismatic community. Through prior hardbound books, both Kamal Ahwash and Brian Greer advanced the knowledge and collector base for Liberty Seated Dimes. I've decided to take a different approach with the 3rd book given the advancements in computer and internet technology. Contained within the web-book is wealth of new information about Seated Dime die varieties and die states in a format that organizes the previous die varieties defined by Ahwash and Greer. There is an update to historical Coin World pricing trends, and great Seated Dime photography. Interested numismatists and casual browsers will enjoy access to a vast Liberty Seated Dime die variety collection formed with contributions from many collectors of the series.
