Authentication quality can make or break the value of your item. Some companies use rigorous standards and expert-level methodology—others rely on quick opinions, vague processes, or inexperienced reviewers. Sending your item to the wrong authenticator can lead to incorrect opinions, wasted fees, undervaluation, and long-term credibility issues when you go to sell.
DJR Expert Guide Series, Vol. 142 — How to Vet an Authentication Company (Questions to Ask Before You Submit) gives you the complete, professional checklist used by advanced collectors, dealers, estate managers, and appraisers to evaluate an authentication company before you submit your item. This guide teaches you what questions to ask, how to confirm credentials, how to analyze their methodology, and how to identify red flags that signal unreliable standards.
Inside, you’ll learn how experts:
Identify reputable authentication companies by category (autographs, art, jewelry, watches, documents, coins, memorabilia, antiques)
Evaluate qualifications, background, and professional expertise
Understand their authentication methodology—visual, forensic, material-based, or archival
Confirm whether they provide legally defensible reports or simple pass/fail opinions
Analyze turnaround times, fees, “rush” options, and hidden costs
Determine who actually evaluates your item and whether they sign the findings
Spot major red flags—lack of transparency, unrealistic guarantees, low-cost “instant authentication,” inconsistent results, and generic COAs
Verify real market credibility through auctions, dealers, and collector networks
Volume 142 provides a professional, step-by-step system that ensures you choose an authentication company with confidence—protecting both the integrity and long-term value of your items.
