The Two-Minute Guide to the Professional Coin Grading Service (PCGS)


American Bullion is proud to be a member and Authorized Dealer of the Professional Coin Grading Service (PCGS). Here is a quick overview of who they are, what they do, and why they’re important.

What is PCGS?

PCGS began in 1985 when several rare coin experts realized that the coin collecting market lacks a universal standard to determine coin values and market prices. They aimed to create a third-party appraisal system for a coin’s physical condition that would offer guarantees and work with a nationwide network of reputable coin dealers in order to protect rare coin collectors.

PCGS Coin Grading

PCGS employs some of the world’s top numismatic experts to inspect the characteristics and physical condition of each coin they receive. The graders enter their assessments into a computer database until a consensus is reached on the final grading of the coin. The graders are extensively trained using sets of U.S. and international coins graded on PCGS’ grading standard. To learn more, view PCGS’ full grading standards.

The PCGS NumisCap

The PCGS NumisCap

Each coin PCGS grades gets sonically sealed in a protective and tamper-proof NumisCap holder. A special label is attached containing the coin’s certification number, grade, date, denomination, and unique bar code. The case also has a holographic emblem on the back to prevent counterfeiting. They are designed to be stackable.

The PCGS Guarantee

“PCGS guarantees that all United States and World coins submitted to it shall be graded in accordance with the PCGS grading standards and under the procedures of PCGS. In addition;
