Grading Submission Guide
Submitting your Pokémon cards for professional grading with Ace Grading is easy and environmentally friendly using your Mystery Trainer Box (MTB)! Here’s how:

Step 1: Card Selection and Preparation
- Choose your cards carefully! Select the cards you wish to grade and note the quantity.
- Place each card in a clear protective penny sleeve, then insert it into a semi-rigid holder (Provided within your MTB). This prevents damage during shipping.
Step 2: Online Submission via Ace Grading
- Visit the Ace Grading website (https://acegrading.com).
- Click “Submit” (Centre of screen) to begin your submission.
- Select your desired service level (Due to high demand some services may be shut) and click “Confirm”.
- Enter the quantity of each card and provide the necessary details for each card. (Or save some time and do a simple submission and enter quantity)
- Double-check all information, including your postal address, before confirming your submission.


Step 3: Packaging and Shipping using your MTB
- Pack your cards securely in your Mystery Trainer Box (MTB). Place your cards in the same order as they appear on your submission slip.
- Print your submission slip and include it inside your package.
- Once the cards and submission slip (cut across cut line to remove bottom barcode) are secured in the MTB, put the box within the Jiffy bag you received from us.
- place the submission number and barcode you cut from the bottom of the slip and securely tape it to the outside of your jiffy bag. If you don’t have a printer, clearly write the submission number on the outside of the package and include a note with your submission number inside.
Step 4: Ship your package
- Take your package to your local post office or schedule a courier pickup.
- Send it to: Ace Grading Unit 5, Canada Close Banbury OX16 2RT
