Submission Instructions

  1. Choose a pack of cards and whether you’d like to include bumpers and checkout.
  2. Using the order number you received, document your cards at app.sigmacardgrading.com (preferred) or use our paper form. 
  3. Pack your cards securely. We recommend a penny sleeve inside a top loader. Then stack your cards, add cardboard at the top and bottom, and add painters tape to hold it together, creating a card sandwich! 

  4. Send your cards to us at: Sigma Card Grading, 901 S. Bridge St #256, Dewitt MI 48820
