What Is PCGS and Why Does It Matter?

What Is PCGS and Why Does It Matter? If you have spent any time researching coin buying, you have encountered the acronym PCGS. Understanding what PCGS is and why it matters is one of the foundational pieces of knowledge for anyone buying coins with any seriousness. What Does PCGS Stand For? PCGS stands for Professional Coin Grading Service. Founded in 1986 in San Diego, California, PCGS is one of the two most widely recognized independent third-party coin grading services in the world, alongside NGC. What Does PCGS Actually Do? PCGS performs two core functions: authentication and grading. Authentication means determining whether a coin is genuine. Grading means assigning the coin a grade on the Sheldon scale, from 1 (Poor) to 70 (Perfect Mint State). Once a coin is authenticated and graded, PCGS seals it in a tamper-evident plastic holder called a slab, displaying the coin's type, date, mint mark, grade, and a unique certification number verifiable at PCGS.com. Why Does PCGS Certification Matter? It removes uncertainty about authenticity, documents the grade, provides a common language for buying and selling, and enables registry competition. Commonwealth Coins and Collectibles carries PCGS-certified coins at www.ccandc.gold.
