Whitman Brands announced a landmark acquisition on April 2, 2026, in Virginia Beach, Virginia. The company now holds the rights to the celebrated works of Al C. Overton and Donald L. Parsley. As a result, Whitman has secured the future of Early Half Dollar Die Varieties 1794–1836, the definitive authority on the Capped Bust Half Dollar series.
For specialists in early American silver, this move matters. It protects one of the hobby’s most important research pillars. Just as important, it brings that scholarship under the umbrella of a company with deep roots in numismatic publishing, pricing data, and collector education.

Why the Overton-Parsley Reference Matters
For more than half a century, Overton numbers have served as the universal language for collectors of early American silver. Collectors, dealers, and researchers rely on that system to identify die marriages across the Capped Bust Half Dollar series.
Now, Whitman has added that foundational research to its portfolio. In turn, the company says it will preserve and expand the legacy of scholarship that Al C. Overton began and Donald L. Parsley continued. That pledge carries real weight, because the Overton reference has shaped the way generations of numismatists study and collect the series.

A Family Legacy That Changed the Hobby
The Overton story begins with passion, discipline, and family devotion. In 1967, Al C. Overton published his first full-length book on the series. That work changed the hobby. More importantly, it introduced a systematic method for identifying die marriages.
Overton took a complex field of study and made it accessible. As a result, thousands of collectors could pursue the series with far greater confidence and clarity.
After Al’s passing, his daughter Bonnie and her husband Donald Parsley carried that work forward. Donald had assisted Al with the very first edition, so he knew the project from the inside from the beginning. He then spent more than 40 years studying the series.
Under Donald’s stewardship, and with Bonnie’s steadfast support, the reference advanced through multiple editions. Along the way, the work gained stronger plate quality and better rarity data. Together, the Parsleys turned a family heritage into a monumental contribution to American numismatic history.
Whitman and CDN Continue to Build a Publishing Powerhouse
This acquisition also marks another major step for Whitman Brands.
Whitman began in 1934. The company created the iconic Guide Book of United States Coins, better known as the “Red Book,” as well as the Handbook of United States Coins, or the “Blue Book.” Earlier in its history, Western Publishing owned Whitman as a subsidiary. During that era, Whitman helped bring coin collecting to the masses through its famous blue coin boards. Later, those boards evolved into the folders and albums that still define the hobby for many collectors today.
Then the company entered a new phase. In 2023, CDN Publishing acquired Whitman, and then merged the companies into Whitman Brands. Collectors know CDN as the publisher of the Greysheet. The company has also led the industry in wholesale pricing data since 1963.
Whitman kept building from there. In 2024, the company acquired the rights to the entire Friedberg Collection, including Paper Money of the United States, Gold, Coins of the World, So-Called Dollars, and Early Dated Coins of Europe. At the same time, Whitman also acquired the industry-standard Friedberg Numbering System.
Last year, Whitman launched a completely reimagined and redesigned 2026 edition of the Red Book.
That edition integrated industry-standard, Greysheet-based retail market values in up to nine grades for more than 12,000 coins, tokens, medals, sets, and other collectibles.
Today, Whitman operates as one company under the leadership of John Feigenbaum, President and CEO of Whitman Brands. From that position, the company continues to provide authoritative content, market insight, and trusted experiences to collectors, dealers, and institutions worldwide.
John Feigenbaum on the Importance of the Deal
Feigenbaum placed the new acquisition in clear context.
“The Overton-Parsley research is the bedrock of early half-dollar collecting,” he said. “It is a profound honor to be entrusted with Al and Donald’s legacy. We look forward to utilizing our digital and print resources to keep this essential data at the fingertips of every specialist in the field.”
That statement speaks directly to the importance of the work. It also points to Whitman’s next move. The company does not plan to let this research sit still. Instead, it intends to extend the reach of the material through both print and digital channels.
What Comes Next
Whitman plans to announce future editions and digital integrations of the Overton-Parsley data in the coming months.
For collectors, that promise could open the door to broader access and stronger usability. For the hobby, it signals continuity. The research that specialists trust will remain in active hands, and a new generation of collectors will likely meet the Overton-Parsley standard through fresh formats and expanded tools.
