Grading prep guide

Prepare your cards the right way

How you store, sleeve, package, and ship your cards directly affects whether they arrive at the grading company in the same condition they left your hands. This guide covers every step.

01 / SLEEVES

Penny sleeves & perfect fits

The first layer of protection goes on before anything else. Getting this wrong introduces micro-scratches before the card ever leaves your house.

Use a fresh penny sleeve

Always use a brand-new penny sleeve. Reused sleeves carry dust, debris, and micro-scratches from previous cards. A sleeve that cost a fraction of a cent is not worth risking a PSA 10.

Perfect-fit sleeves for high-end cards

For High End Vault submissions — refractors, 1/1s, serial-numbered cards — add a perfect-fit sleeve under the penny sleeve. Perfect fits hug the card tightly and eliminate movement inside the outer sleeve.

Slide in face-down

Insert the card face-down into the penny sleeve so the open end is at the bottom. This keeps the card face away from the sleeve opening and reduces the chance of surface contact during insertion.

No tape on sleeves

Never tape a sleeve closed. Tape residue can transfer to the card surface and is an instant condition flag. If you need a sealed sleeve, use a team bag instead.

02 / HOLDERS

Top loaders & card savers

Once sleeved, your card needs a rigid holder to survive handling and shipping. Choosing the right thickness matters more than most collectors realize.

Match the top loader to the card thickness

Standard cards fit a 35pt top loader. Thicker cards — chrome refractors, prizms, relics, patches — need 55pt, 75pt, or higher. A card rattling inside an oversized top loader will arrive with corner and edge damage.

Card savers for grading submissions

PSA and BGS prefer Card Saver I semi-rigid holders over hard top loaders because they're easier to remove without touching the card. If you're submitting directly to a grading company after your pre-screen, switch to Card Saver Is.

Check the top loader for scratches first

Inspect the inside of the top loader before inserting your card. Scratched or dirty holders transfer damage. If in doubt, use a new one.

Secure the opening with painter's tape

Once the sleeved card is in the top loader, fold a small piece of painter's tape over the open end. Painter's tape peels cleanly and holds the card in place without leaving residue on the sleeve or card.

03 / HANDLING

Handling without damage

Most condition damage happens during handling — not shipping. These habits protect your cards every time you touch them.

Hold by the edges only

Never touch the face or back of a card with bare fingers. Skin oils leave prints that can affect surface grades. Hold the card by its edges with light pressure, or use cotton gloves for your most valuable cards.

Work on a clean, soft surface

Place a microfiber cloth or clean felt mat on your work surface before handling cards. Hard surfaces — desks, tables, glass — cause edge and corner damage if a card slides or is set down at an angle.

One card at a time

Never stack unsleeved cards or fan them like a hand of playing cards. Card-on-card contact is one of the most common causes of surface scratches and edge wear.

Avoid humidity and direct light

Prepare cards in a cool, dry environment away from direct sunlight. Humidity causes warping and curling. Even a few minutes under a bright lamp can affect a card's surface sheen.

04 / PACKAGING

Packaging for shipment

A well-packaged card can survive a rough postal journey. A poorly packaged one won't survive the first sorting machine.

Team bag the top loader

After taping the top loader closed, slide it into a team bag and seal it. This adds a second layer of protection against moisture and keeps the top loader from shifting inside the outer packaging.

Use bubble mailers for single cards

For one to three cards, a rigid bubble mailer works well. Place the team-bagged top loader between two pieces of cardboard cut slightly larger than the holder, then slide the sandwich into the bubble mailer.

Use a small box for larger submissions

For Value tier submissions (2–25 cards), use a small rigid box. Stack top-loaded cards vertically — not flat — with bubble wrap or foam padding on all sides. Cards packed flat can shift and collide.

05 / SHIPPING

Shipping & insurance

How you ship is as important as how you package. The right service and the right insurance protect your investment from door to door.

Always use tracking

Never ship cards without a tracking number. USPS First Class, Priority Mail, UPS, and FedEx all include tracking. A tracking number is your only proof of delivery if something goes wrong.

Insure based on card value

APSB4G does not insure any items at any time. You are responsible for selecting your own level of insurance through your local post office or your own mailing preferences. For high-value cards, declared value insurance through USPS, UPS, or a third-party insurer like Collectibles Insurance Services is strongly recommended.

Photograph everything before sealing

Before you seal the package, photograph the card in its sleeve and holder, the sealed package, and the shipping label. This documentation is essential for any insurance claim.

Avoid shipping in extreme weather

Heat and cold affect cards in transit. Avoid shipping during heat waves or freezing temperatures when possible. If you must ship, add a silica gel packet to absorb moisture and consider expedited shipping to minimize transit time.
