Proprietary Grading Software

Patent Pending

DSG grades all cards using our own proprietary program which has been developed over the course of the 20 years experience the founders have in the card grading industry. The software allows our graders to quickly, accurately, and consistently grade cards by assessing flaws and damage on each of 8 card zones, then entering that data into the program. The information is then calculated using an algorithm which ensures that your card will get the correct grade regardless of which of our graders is making the assessment, or how many times that same card is graded.

Online Grade Report

Our encapsulations feature a QR Code on the back that is unique to your graded card. Scan the code with your smart phone and an online DSG Grade Report (patent pending) will appear! The grade report includes images of both the front and back of your card, along with a detailed report that shows exactly where the flaws and damage are located and their degree. This is an industry first and it gives transparency to the grading process that has up until now, been shrouded and highly subjective. You are able to view exactly how the card has been assessed and why it received it’s grade!
