Hello!
We're happy to announce that the wait is over! We've found partners and can now offer an official Cardmarket Grading service for our users. This is a fully developed and complete grading service that offers an official number grade on graded cards, ensuring their value for trading. You can find the service on our new grading page, along with detailed instructions on how exactly you can order a card grading on Cardmarket.
We hope you enjoy the new service and we look forward to seeing your Cardmarket-graded cards down the road!
Your Cardmarket Team
