About CGC

Certified Guaranty Company (CGC) was founded in 1999 as the first independent, impartial, expert third-party grading service. Since then, CGC has expanded into authorized witnessed signatures for photos and grading and encapsulation of magazines. As an independent member of the Certified Collectibles Group (CCG) — an umbrella company comprised of the world's leading companies dedicated to certifying, grading and encapsulating collectibles — CGC is dedicated to grading collectibles with integrity, accuracy, consistency and impartiality. Other companies under CCG include Numismatic Guaranty Corporation (NGC), the leading grading service in rare coins, and Paper Money Guaranty (PMG), the leading currency certification service.

A Commitment to Hobby Enrichment

Our commitment is to enhance the collecting experience of a growing number of autographed memorabilia collectors for decades to come. To accomplish this, CGC will work diligently toward these goals:

To build trust... by increasing the confidence of autographed memorabilia collectors and new market participants.

To build interest... in the collecting public through education and resource development. By expanding hobby knowledge, we encourage signed memorabilia collectors of all levels to explore the hobby and increase their expertise.

To build consensus... around CGC practices and procedures based on market-wide research and input from autographed memorabilia collectors and dealers nationwide.

To build transparency... by revealing the unique characteristics of each signed comic, photo or magazine we certify, so collectors are better informed about the items they purchase.

To build a better market... to provide buyers with expertly and accurately graded and authenticated autographed memorabilia, so they can purchase with confidence, and to assure fair prices for sellers.
