How to Prepare Your Card For Grading

Getting your cards ready for grading is a big step for any collector. It’s not just about keeping them safe. It’s about giving them the best shot at a high grade.

At TGA, we grade thousands of cards. And we want to help you get the best results.

In this guide, we’ll show you what our professional graders look for. We’ll talk about the four key areas: centering, corners, edges, and surface. Then, we’ll walk you through how to inspect, clean, and protect your cards before sending them in.

Let’s get your collection ready to score big!

Key Elements of Card Grading

The primary factors on which the card grading is divided are centering, corners, edges, and surface condition.

Centering

Centering is a measure of how well the image is centered in the card border. Perfect centering is with uniform borders, and misalignment is a penalty.

How to measure centering:

Centering on all vintage cards is judged also by border size, so use a ruler or centering tool if the border size is noted. 50/50 centering cards get graded the highest, while cards that have 60/40 centering or worse have grades deducted. While current cards frequently feature stronger centering, it's an aspect that anyone should still be aware of.

Corners

Similarly, the corners of your card should be sharp and crisp. This plays an important role in determining the grade of the card. An excellent card has soft or raised corners.

  • Identifying corner defects: Look at each corner under good light and magnification. Small blemishes also factor into the final grade.
  • Common Corner Wear Issues: Corners can exhibit slight wear from storage, handling, and or manufacture. The grade is usually based on the worst corner, so check all four of them carefully.

Edges

The edges of high-level cards are clean-cut and even, and the cuts do not stray from what would be considered the perfect cut.

  • Checking the Edge: Check for chipping, cut marks, or roughs. Modern cards should have sharp, clean edges, while vintage cards should show natural wear.
  • Edge Damage: Chipping is especially evident on dark-bordered cards and will reduce a card's grade significantly.

Surface

The surface quality is paramount in grading cards. This will include any rips, holes, etc., on the front, as well as the back of the card.

Surface Check: Look for print lines, scratches, smudges, and creases.

Tips for Use of Lighting: Check defects in many angles of light, and some defects may not be normally seen when lighting is not present.

How to Get Your Card Ready for Grading

Step 1: Inspect the Card

A good look under the right light will pinpoint every possible condition issue before you turn in your list.

  • Surface scratches: Turn the card in the light to look for any fine scratches or deeper scuffs.
  • Corners: Magnify them to see if they are rounded, bent, or chipped.
  • Chipping at the edges: Look at all edges very carefully, especially for any nicks, cracks, or roughness.
  • Center: Measure card borders precisely.
  • Print flaws: Examine for factory errors like lines or smudges.

Step 2: Gently Clean the Card (If Necessary)

Only clean if you observe any obvious dirt or marks that can be gently wiped away.

A gentle cloth or pantyhose may be used.

Wipe in straight lines from end to end and avoid cross wiping. Do not wipe with strong chemicals.

If you're unsure about cleaning the card, it's best to submit it as is.

Step 3: Use a Penny Sleeve

The first line of defense is the flimsly plastic sleeves called penny sleeves.

Slide the card gently to avoid bruising at the corners.

We suggest you use new, clean sleeves for submissions.

Step 4: Place in a Card Saver/Toploaders

Hard holders offer a higher degree of protection from the card while still providing access for grading.

Card savers are highly recommended; toploaders will also be acceptable.

The card should slide in smoothly without any obstructions.

Step 5: Label and Organize (If Submitting Multiple Cards)

  • Number each card according to your submission form.
  • Organize cards by set, year, or what grade you anticipate them being.
  • Create a master list to simplify your verification and that of your grading team.
  • Use painter's tape to ensure your card does not move in the hard plastic during transport.

Step 6: Secure Packaging for Shipping

  • Pack in a sturdy shipping box, along with protective cushioning, such as bubble wrap or foam.
  • Strap the cards, so they won't be shaking around during travel.
  • Put your submission forms in a sealed bag for extra safety.
  • Employ tracking and insurance, especially for expensive items.
