About Us

We are a fully insured coin grading service that prides itself on conservative grading. Our mission is to take the uncertainty out of third party grading by providing a safe and stable grading standard for the public to rely and trust in. NTC has set industry wide standards in the following key areas:

Providing solid grades for all coins.

At NTC we use three graders. Each grader specializes in a particular field of grading from modern coins to gold, silver, copper and varieties. Our graders are the best in the industry and have handled almost every U.S. coin in the Red Book and have a total of 60 years of combined grading experience.

Attractive and secure holders.

Our design/engineering team has designed and engineered the most attractive and durable holder in the market. Our holders have undergone a rigorous two year development process and every structural and design element has been meticulously tested. First we wanted to make sure the holder would compliment the coin and bring out all the beauty the coin has to offer, so we chose a simple but high tech insert to our holder.

Our modified clear acrylic resin case offers impact strength which is much stronger than general-purpose acrylic resins making it one of the strongest, most durable holders on the market. In addition, it has imbedded ultra violet protection to shield the sun's rays and protect the coin from toning. The insert is a non PVC material that will not react with the coins metal and cause change in color.

Our label is bar coded and serial numbered to prevent counterfeits and duplicates, providing easy inventory management for you.

Open access to everyone.

Our service is open to all. You do not have to be a dealer nor do you have to submit your coins through a dealer to receive world class grading of your coins. You can submit your coins in total confidence using our online submission form. You will get reliable turn around time on all of our services combined with prompt, courteous telephone customer support.
