American coin grading organization

Professional Coin Grading Service (PCGS) is an American third party coin grading, authentication, attribution, and encapsulation service founded in 1985. The intent of its seven founding dealers, including the firm's former president David Hall, was to standardize grading. The firm has divisions in Europe and Asia, and is owned by parent company Collectors Universe. PCGS has graded over 42.5 million coins, medals, and tokens valued at over $36 billion.

Established in 1985 by a group of seven dealers, which included David Hall, the former president of the firm, PCGS aimed to create authoritative grading standards with a firm commitment to ensuring the accuracy of grading through guarantees. The firm has since started grading foreign coins and established divisions in Europe and Asia, and was purchased by Collectors Universe.

The PCGS holder, or a Coin slab which is made of clear, inert plastic and is stackable. Anti counterfeiting measures include a hologram on the back, markings within the holder, and Near Field Communication (NFC) chip embedded in some holders. Printed on the front of the blue paper insert is the coin's type, denomination, grade, attribution, pedigree (if any), serial number, Universal Product Code (UPC), and other pertinent information. First generation PCGS coin holders are smaller and lack the raised stackable edges of later issues. Their insert was printed on plain white paper. In some of these early holders, the coin will be loose enough to produce noise when the holder is handled, thus their "rattler" nickname. Through an analysis of the population reports provided by both PCGS and NGC, estimations of coin rarity have been facilitated. By examining these databases over time, certain coins previously believed to be rare have turned out to be surprisingly common, while others assumed to be common have revealed themselves to be more scarce than initially thought. Numismatic professionals closely follow these population reports because they understand that the reported numbers can be affected by practices such as multiple submissions of the same coins. This involves removing coins from their holders and resubmitting them in the hope of achieving a higher grade. Consequently, population figures might be artificially inflated. Conversely, there can be instances where population figures appear lower than expected due to the hesitancy to submit less valuable coins for grading, especially when the cost of the service exceeds the coin's value.

PCGS offers a complimentary, partially accessible online compilation of U. S. and foreign coin values. These values pertain exclusively to coins that have received PCGS certification. The data for these values is sourced from various channels, including dealer advertisements and price lists, realized auction prices, and transactions that occur during trade shows.

In 2001, PCGS introduced its Set Registry program, which is accessible at no cost. This initiative features an online leaderboard where collectors can engage in friendly competition across numerous potential sets, all comprising PCGS graded coins. Currently, the Set Registry program hosts over 113,000 sets. Each coin in a set is given a value computed by its relative scarcity. A version of the Registry is also maintained by PCGS' main competitor, NGC.

A comprehensive survey of major coin dealers, carried out in collaboration with the Professional Numismatists Guild (PNG) and the Industry Council For Tangible Assets (ICTA), disclosed that PCGS received the dealers' top tier "Superior" rating, which was the highest rating granted to any service. Among the other 10 grading services scrutinized in the survey, only the Numismatic Guaranty Corporation (NGC) also attained the "Superior" rating. The survey participants, consisting of coin dealers, were invited to offer their professional assessments of 11 grading services. Their evaluations were based on 12 different criteria, each assigned a specific weight. Factors like grading accuracy and authentication were considered. Respondents were asked to rank each category on a scale of 10 points, spanning from the lowest ranking of "Unacceptable" to the highest rating of "Outstanding".

In 1990, the Federal Trade Commission initiated a civil action against PCGS, asserting that the company had made exaggerated claims in its advertising. A resolution was reached through a settlement in which PCGS did not officially acknowledge any wrongdoing. However, as part of the settlement terms, PCGS agreed to a five year period during which its advertising would be subject to review and also consented to incorporating a disclaimer within its advertisements.
