The Print Edition is planned for late Spring 2014.

This book builds on the extensive experience of the authors, and their multiple decades of collecting this often-neglected and under-appreciated series. This highly-illustrated book presents new insights on 20-cent pieces, and offers the most comprehensive information ever assembled on all aspects of this short-lived coin. It is hoped that this reference will provide existing collectors with a wealth of new information, and instill interest and enthusiasm for an entire new set of collectors as well.

Table of Contents

1. History of the Series
A detailed history of the series, from Thomas Jefferson's original proposal for a "Fifth" of a Dollar (later called "double disme"), several additional attempts in the 1800s, to the final authorization in 1875, its rejection, and ultimately the abolishing of the denomination in 1878.

2. Design Evolution -- Patterns of 1874-1875
The evolution of the design through the patterns of 1874 and 1875, including the players, the different designs, and communicaton between Mint Director Linderman and Superintendent Pollock. Rarity and collectability information is also discussed.

3. Theories on 20-cent Misplaced Dates
Well known to those who have studied the series, there are surprisingly many instances of misplaced dates (tops of digits below the date in the denticals). This chapter presents a new theory on how these misplaced dates may have been created, and evidence is presented to demonstrate that this theory is, at least, plausible.

4. Collecting Double Dimes
People collect this series in many different ways, including by type, by year, by mint, and many others. More and more collectors are building complete sets, and also focusing on varieties. A recent trend of Liberty Seated collectors is to study die marriages. This chapter discusses the different manners in which one can collect 20-cent pieces, and offers suggestions and options for doing so.

5. Grading
Although the 20-cent piece is a Liberty Seated coin, grading this series is fundamentally different than grading the other denominations. A different obverse model was used, and the reverse is much more three-dimensional than the other Liberty Seated Series, necessitating different grading standards. Strike also highly affects appearance. This chapter offers grade descriptions and photos of both well-struck and weakly-struck coins to illustrate the differences.

6. Date-by-date Analysis, including all Known Die Marriages
Along with a brief history for each year, each date and mint is described, including mintages, strike, major varieties, overall availability, rarity ratings, and pricing commentary. Following the summary information, a detailed listing of all known die marriages is presented, with high-resolution photos of identifying die markers, and comments on relative availability. Includes expanded material on the 1875-S Branch Mint Proof, and the 1876-CC.

7. Errors
Double dime errors range from very scarce to extremely rare. This chapter describes and illustrates the different types of errors known to exist on 20-cent pieces. From minor to spectacular, these blunders are challenging, and sure to entertain.

8. Exonumia
In years past, many things were done to coins, creating a wealth of interesting and unique coin-related collectibles. Love tokens, countermarked coins, elongated coins, and clothing accessories/jewelry are some of the unusual items made from 20-cent pieces, and all are scarce to rare. This highly-illustrated chapter also discusses rare contemporary counterfeits as well.

9. Mintages and Survival
This chapter examines the records of the official melting of twenty-cent pieces over the course of many decades, beginning in the 1870s until well into the 20th Century, and the estimates for survivorship of the different issues, leading to the various levels of scarcity seen today.

10. Anecdotes
This chapter rounds out the book with stories, all involving 20-cent pieces. From the debut of a previously unknown example of the very rare 1876-CC, to the discovery of discarded dies in Carson City, this entertaining material presents a different perspective than normally seen in a book about coins. It is about history, and it is about the excitement of discovery.
