Get Perfect Centering, Every Time

 ✅ FREE SHIPPING

Introducing the Gem10 Sport and Trading Card Centering Tools – the only centering tools you'll ever need to accurately assess whether your sports or trading cards are perfectly centered or slightly off. If you're aiming for that elusive Gem Mint 10 from PSA, SGC, BGS, CGC, TAG, or any other grading company, this is your must-have tool.

Why Choose the Gem10 Centering Tools?

These premium-quality tools combine two precision instruments in one:

• A millimeter-based centering grid for pinpoint accuracy

• Dual-sided rulers printed into the sides of the tool, giving you all-in-one measurement functionality

Unlike flimsy and cheap alternatives, the Gem10 Centering Tool is built to last. Made from durable, thick laminate and rounded at the corners to protect both your cards and your hands, this tool is designed with collectors and graders in mind. The added laminate overlay ensures long-term durability and helps preserve both the print and your valuable cards.

Eliminate Costly Mistakes

With the Gem10 Centering Tools, you can:

• Stop guessing and start accurately measuring card centering

• Avoid sending in cards that won't grade a Gem Mint 10

• Save time and money by submitting only your best-centered cards

Whether you're sending cards to PSA, BGS, SGC, CGC, BLG, TAG, or any other top-tier grader, this tool helps you make smarter submission choices.

Please Note: While these tools offer exceptional accuracy, grading is still a human process involving subjective decisions. The Gem10 Tools can't override a grader’s judgment—but it can give you the best shot at success.

Choose the Right Background for Your Cards

For years, collectors have only had access to black-printed centering tools—which work well for light-colored cards but become nearly unreadable when placed over dark or black cards. Gem10 changed that.

We’re proud to be the first to offer a white-printed laminate, specifically designed to solve this long-standing issue. Now, no matter the card’s background, you’ll be able to clearly see measurements and ensure accurate centering every time.

• Black laminate is perfect for cards with light backgrounds

• White laminate gives clarity when measuring cards with dark or black backgrounds

• Best of all, YOU GET BOTH!

Designed with Card Safety First

All Gem10 products are manufactured using archival-safe materials that won’t damage or degrade your cards over time. Every detail, from the print quality to the protective laminate, is chosen with your collection’s safety in mind.
