[5][8] The firm has since started grading foreign coins and established divisions in Europe and Asia, and was purchased by Collectors Universe.

This process involves grading, authenticating, attributing, and encapsulating these coins in transparent, airtight plastic holders.

[10] 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.

[5][8] PCGS was at one point named the official grading service of the Professional Numismatic Guild; during that time, the PNG logo was included on the holder.

The free site publishes information about all federal and most non-federal U.S. coin issues, including their rarity statistics, PCGS Price Guide values, population data, public auction performances, die varieties, and photographs.

This initiative features an online leaderboard where collectors can engage in friendly competition across numerous potential sets, all comprising PCGS-graded coins.

[21] 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.

[22] In 1990, the Federal Trade Commission initiated a civil action against PCGS, asserting that the company had made exaggerated claims in its advertising.
