Our ambition is to bring quantitative data gathering and analysis to the subjective world of collectibles for grading Coins,
Trading cards, Banknotes, and Stamps.

Our determination is driven by our knowledge of technology and the benefits it provides to our society, in a way of cost reduction,
access to information and data storage.

Our goal is to bridge the gap between the generation of potential collectors with technology thereby paving the way for the
average person to participate in the world of collectibles without extensive knowledge or education, free from human bias,
manipulation or pressure.

Please refer to our F.A.Q. section, to review Defining Quantitative Coin Grading

The definition of the term “QCG Certified”, refers to collectibles, in this case coins that have been analyzed using QCG’s proprietary technology. Our “Patent Pending” technology embraces both hardware and software, that has been calibrated to a set of repeatable standards used to measure any coin’s physical attributes that define a Sheldon Grade. Using the American Numismatic Associations, published grading standards for the United States Coins, and N.C.I. Grading Guide as a template, QCG has developed a repeatable process that is guaranteed to produce unique quantitative data results for any defined coin that has a preprogrammed recipe for the OCS-200 based on the coin’s metallurgy, type, and series.

QCG guarantees that we will provide quantitative data on your scanned coin in 15 minutes or less, or your transaction service fee will be completely refundable, no questions asked. Time clock starts for each coin when coin images have been accepted by QCG central server, and the time clock ends when the quantitative results have been delivered to the customers supplied email. Refunds automatically applied by QCG to your wallet account from QCG recorded time-card data, customer requests need to be sent to [email protected]

QCG offers its customers the only 3rd Party grading service raw state coin guarantee in the world. Scan your raw state coin once using the OCS-200 scanner, using our service, and you can scan that same coin as many times you need in the future, regardless of change of coin ownership or grade, with no transaction fee charge. QCG Coin ID number is required.
