Why Proper Care is Important for Graded Slabs
Graded slabs do more than just protect your cards from wear and tear. They play a crucial role in maintaining the market value of your collectible. Keeping the slab in good condition means your card remains safe from environmental factors such as dust, humidity, or temperature fluctuations. Furthermore, well-maintained slabs preserve their resale value. In short, proper care helps ensure that your investment remains valuable!
Step-by-Step Guide to Caring for Your Graded Slabs
1. Handling Graded Slabs
Graded slabs should always be handled with care. Oils and dirt from your fingers can leave smudges and marks on the slab’s surface, affecting its clarity and appearance. Instead of handling them directly with your hands, use slab sleeves to protect the surface. These sleeves fit perfectly over your graded slabs and act as a protective layer, preventing any potential damage. This simple step will protect both the card inside and the slab’s exterior while keeping your collection pristine.
2. Storing Graded Slabs
To preserve the integrity of your graded slabs, store them in a cool, dry environment. Extreme temperatures and humidity can warp the slab or damage the card. Here are some tips for storing your graded slabs:
- Keep slabs away from direct sunlight, as UV rays can cause the acrylic to degrade and affect the card inside.
- Use protective storage boxes designed for graded slabs to keep them safe from dust and physical damage.
- Store slabs in a climate-controlled environment with temperatures between 65°F and 70°F and humidity levels around 40% to 50%.
3. Displaying Graded Slabs

If you plan to display your graded slabs, opt for UV-protective display cases. This will shield the slab from harmful rays and dust, while allowing your collection to shine. Make sure the display is kept away from areas prone to temperature fluctuations or humidity.
4. Cleaning Your Graded Slabs
Cleaning graded slabs should be done with extreme care. Here’s how:
- Use a microfiber cloth to wipe down the surface of the slab gently.
- Avoid any cleaning solutions or harsh chemicals, as these can damage the acrylic.
- Never attempt to clean the card inside the slab. If the card is dirty or needs attention, consult a professional for safe cleaning options.
5. Avoid Common Mistakes
There are a few common mistakes collectors make that can damage their graded slabs:
- Storing slabs in extreme temperatures: This can cause the acrylic to warp, or worse, damage the card inside.
- Not using slab sleeves: Handling graded slabs without protection can leave fingerprints or smudges. Using slab sleeves ensures that the slab stays clean and safe from any direct contact.
- Using improper storage: Keeping slabs in cardboard boxes or unprotected areas can expose them to dust and accidental bumps.
