Even if a card is in mint condition, poor centering can drastically reduce its grade and value. With Card Centering Calculator, you can precisely measure centering ratios, ensuring you make informed decisions about submitting cards for professional grading. Who Should Use Card Centering Calculator 1. Card Collectors: Ensure your trading or sports cards meet professional grading standards, preserving and potentially increasing their value. 2. Sellers & Traders: Verify centering to maximize the worth and appeal of your cards before selling or trading. 3. Buyers: Quickly assess centering on potential purchases to avoid investing in off-centered cards that might lower their grading potential. Note: Card Centering Calculator focuses exclusively on measuring centering ratios. Keep in mind that professional grading companies like PSA, BGS, CGC, SGC, TAG, and ACE also evaluate other factors, including edge wear, surface scratches, dents, dings, and overall condition. This app does not assess these additional grading criteria.
