Gradetor is an AI pre-grading service for collectors. You take photos of a coin, banknote, trading card, stamp or comic, and the AI estimates its grade on the scale collectors already use, explains the condition criteria behind it, points out defects and tells you whether professional grading is likely to be worth it.
No. Gradetor gives an estimate based on your photos, not a certified grade. Only a professional grading service that examines the item in hand can issue an official grade and slab. Use Gradetor to decide which items to submit, to check items before buying or selling, and to keep track of your collection.
No. Because Gradetor works only from photos, it can't tell a genuine item from a high-quality replica with 100% certainty. The AI examines every detail it can see, such as design, lettering, printing, edges and surfaces, points out anything that suggests a replica, alteration or restoration, and gives its opinion on authenticity. That opinion is never a guarantee and is not financial advice. For valuable items, always have them authenticated by a professional grading service or a trusted dealer.
Gradetor uses the latest AI vision technology and gives a likely range, not just one number, so you can see how certain the result is. Accuracy depends a lot on the photos: sharp, well-lit pictures of the front and back give the best results. Some issues, like light cleaning or small hairlines, can be hard to see in any photo.
Coins, banknotes, trading cards (TCG and sports), stamps and comics, each on its own grading scale. Coins and banknotes are graded on the 1–70 scale and also in the grading system collectors use in your country, such as UNC, XF and VF in the US and UK, vz and ss in Germany, or SUP and TTB in France.
Place the item on a plain, dark background, use soft even light without glare, and fill the frame. Photograph both sides straight on. For coins, a second photo at a slight angle helps the AI judge luster and surface marks. Cards and banknotes can stay in a clear sleeve or holder if it isn't scratched.
No. Grades you buy never expire, and there is no subscription. One grade is used for each successful report; photos that can’t be graded are never charged.
No. The Gradetor web app works in the browser on phones, tablets and computers. Sign in with Google or Apple and start grading.
Important notice: All grades, condition scores, identifications and authenticity opinions in Gradetor are AI-generated from your photos and are for informational purposes only. They are not certified grades, appraisals or financial advice, are not guaranteed and may contain errors. Gradetor does not authenticate items and does not guarantee that any item is genuine: counterfeits, replicas, altered or restored items may not be detected from photos. Gradetor is not affiliated with any professional grading service. Always have important items authenticated and verified by a professional grader or dealer before buying, selling or insuring them.
