Book Introduction From a lifetime collector, ANA Gold member & contributor to The Numismatist – get the next article in May of 2026.This reference is designed for advanced coin collectors and researchers seeking accurate, verifiable data on U.S. error coins. It presents over 4,000 individually cataloged listings of encapsulated error coins, all documented from major live auctions across Florida, providing a clear view of real-world availability and market behavior.With the exception of images used to define error classifications, this guide intentionally excludes photographs of individual error coins. Displaying a single example—such as a 1972 doubled die—would be misleading, as that date alone includes ten distinct varieties, nine carrying PCGS Fiaz–Stanton attributions. Instead, the focus is on comprehensive listings that demonstrate the true scope and frequency of doubled dies and RPM/OMM varieties.The book includes 81 distinct error coin types, each supported by photographs and clear technical descriptions to establish accurate identification standards. For expanded visual diagnostics and attribution confirmation, collectors are encouraged to reference Variety Vista, which documents every known doubled die and repunched mintmark.Error coin listings in this guide can be directly matched to illustrated examples on Variety Vista for precise attribution.Built on decades of market study, this guide serves as a specialized error coin research and price reference, enabling serious collectors to identify, evaluate, and understand genuine error coins with professional confidence.Inside:81 types of error coins described with photos.8 doubled die types which collectors need to avoid missing these errors.4,178 real auction results from 16 years of data collection.Over 135 RPM listings so collectors know what to look for and the auction values.Glossary of 128 essential termsThe only self-published guide with an email contact.Forget shallow guides that highlight only a handful of well-known, inaccessible errors.
