Ancient Roman silver denarii are among the most frequently counterfeited ancient coins precisely because age, wear, and stylistic variation create false confidence. Collectors often assume that rough surfaces, porosity, or uneven detail reflect centuries of circulation rather than modern fabrication, while portrait style and legends are trusted far beyond their reliability. Understanding how struck versus cast surface behavior differs matters because manufacture method—not appearance—determines authenticity, and surface misinterpretation is one of the most common causes of costly misidentification in ancient coin collecting.
DJR Expert Guide Series, Vol. 2295 gives you a complete, beginner-friendly, non-destructive workflow for distinguishing struck ancient Roman silver denarii from cast counterfeits using professional surface diagnostics. Using structured observational techniques—no specialized tools, no risky handling, and no prior experience required—you’ll learn how professional authenticators analyze metal flow, surface texture, edge behavior, strike pressure evidence, and aging contradictions to identify casting with confidence before style or attribution are even considered.
This guide is intended for situations where relying on appearance, wear, portrait style, seller assurances, or informal opinions creates unacceptable risk. It is most often used before purchase, resale, insurance documentation, or estate transfer when authenticity confidence, attribution credibility, and future liquidity may materially affect value and reputation. Using a structured professional framework at this stage helps prevent assumptions that are difficult or impossible to correct later.
Inside this guide, you’ll learn how to:
Understand how genuine Roman silver denarii were struck and why manufacture matters
Identify directional metal flow that survives wear on authentic struck coins
Recognize granular texture and porosity patterns unique to cast counterfeits
Evaluate edge and rim behavior for seams, filing, and mold evidence
Distinguish strike-based relief transitions from cast softness
Detect tooling and surface “improvement” used to disguise casting
Identify artificial aging and patination that contradict surface physics
Understand why wear patterns frequently mislead collectors
Apply high-impact cast counterfeit red flags decisively
Determine when professional authentication is required
Whether you are evaluating a single ancient coin, reviewing a potential acquisition, managing an inherited collection, or preparing documentation for resale or insurance, this guide provides the professional, authentication-first surface framework needed to protect value and credibility in one of the highest-risk areas of ancient numismatics.
