Grading sports cards is an essential process that determines their condition, authenticity, and market value. Whether you’re a collector or planning to sell your cards, understanding the grading criteria is crucial. Professional grading companies, like PSA, Beckett (BGS), and SGC, assess sports cards based on several key characteristics, assigning them a grade that impacts their desirability and worth.

This guide explains the characteristics graded on sports cards, helping you understand what evaluators look for and how to assess your collection before submitting it for grading.

Why Grading Matters

Grading provides a standardized evaluation of a card's quality and authenticity. This not only assures buyers of its value but also protects sellers by formalizing its condition. A high-grade card is more attractive to collectors and typically fetches a higher price on the market.

The Key Characteristics Graded on Sports Cards

When professional graders evaluate sports cards, they focus on several distinct characteristics. Each plays a vital role in determining the card’s overall grade, which usually falls on a scale of 1 to 10.

1. Centering

Centering refers to how well the image, text, and borders on the card are aligned. Ideally, the design elements should be perfectly centered, with equal border widths on all sides.

• Poor Centering: A card with uneven borders or an off-center image can significantly lower its grade.
• Measurement Standards:
  • PSA allows minor centering imperfections (e.g., 60/40 front centering for a PSA 9).
  • BGS provides a subgrade specifically for centering.

How to Check Centering:

Examine the card’s borders and use tools like centering templates or rulers to measure the alignment.

2. Corners

The condition of a card’s corners is one of the most scrutinized characteristics. Sharp, clean corners without any bends or wear are essential for achieving a high grade.

• Sharp Corners: Perfectly square, clean edges are indicative of a card in mint condition.
• Damaged Corners: Frayed, bent, or rounded corners significantly reduce a card’s grade, especially in modern cards.

How to Check Corners:

Inspect the corners under a magnifying glass to spot imperfections. Handle the card carefully to avoid additional damage.

3. Edges

Card edges are another critical factor in grading, as they are prone to chipping and wear over time. Flawless edges indicate that the card has been well-preserved and minimally handled.

• Clean Edges: Edges should be free of nicks, chipping, or discoloration.
• Damaged Edges: White chipping, scratches, or roughness along the borders can lower the card's overall grade.

How to Check Edges:

Run your fingers gently along the edges or examine them closely to identify any imperfections. Edge damage is particularly common in foil cards.

4. Surface

The surface of a sports card encompasses both the front and back and should be free from blemishes, scratches, or stains. Graders look for consistent gloss, color vibrancy, and absence of imperfections.

• Pristine Surface: A clean, glossy surface with no visible flaws contributes to a higher grade.
• Common Issues: Fingerprints, smudges, scratches, dents, and print lines are common reasons for lower grades.

How to Check Surface:

Hold the card under bright light to spot surface imperfections. Avoid touching the card’s surface directly to prevent fingerprints or smudges.

Additional Characteristics Considered

1. Print Quality

For cards with intricate designs or holographic elements, print quality is crucial. Graders evaluate the clarity of text, images, and logos. Cards with misprints, blurred images, or faded colors are penalized.

2. Gloss and Finish

For modern glossy or foil cards, graders assess the uniformity of the finish. Any scratches, clouding, or peeling significantly impact the grade.

3. Authenticity

Grading companies verify the authenticity of the card to ensure it isn’t counterfeit or altered. This includes confirming the manufacturer, year, and design integrity.

4. Serial Numbers and Autographs

For cards with serial numbers or autographs, graders check for legibility and ensure there’s no smudging or fading. Autographs may be authenticated separately or as part of the grading process.

Grading Scale Overview

The characteristics above are evaluated on a detailed scale, with the final grade typically ranging from 1 (Poor) to 10 (Gem Mint).

• Gem Mint (10): Flawless centering, sharp corners, clean edges, and a pristine surface.
• Near Mint-Mint (8-9): Minor imperfections, such as slight off-centering or minor edge wear.
• Excellent (5-7): Noticeable flaws, such as corner rounding or visible surface wear.
• Poor (1-4): Significant damage, such as creases, stains, or heavy wear.

‍

Tips to Improve Grading Outcomes

1. Handle Carefully: Always handle cards by their edges and use protective sleeves to avoid surface damage.
2. Pre-Grade Your Cards: Assess centering, corners, edges, and surfaces at home to identify which cards are worth submitting for grading.
3. Clean the Cards: Use a microfiber cloth to gently remove fingerprints or dust from the surface. Avoid any cleaning methods that could scratch or damage the card.
4. Invest in Protective Supplies: Use semi-rigid holders (e.g., Card Savers) for shipping to grading companies.

Conclusion

Grading sports cards involves a meticulous assessment of centering, corners, edges, surface, and other key characteristics. These factors determine the card’s final grade and, ultimately, its market value.

By understanding what graders look for and taking steps to preserve your cards’ condition, you can maximize their potential and ensure they achieve the highest grade possible. Whether you’re a collector or seller, proper grading can elevate your cards’ appeal and solidify their place in your collection or on the market.
