The Professional Coin Grading Service (PCGS) is a leading organization that evaluates and grades coins based on their condition and authenticity. Founded in 1986, PCGS provides a standardized grading system that helps collectors and investors understand the value of their coins. Each coin is examined by expert graders who assign a numerical grade, which can significantly influence its market price. PCGS also offers encapsulation services, where graded coins are placed in tamper-proof holders to protect them from damage and ensure their authenticity. This service enhances the coins' resale value and provides confidence to buyers. Collectors often seek PCGS-graded coins for their reliability and trustworthiness in the numismatic market.
