Guide 01

Getting Started in the Hobby

Every collection starts somewhere. Some collectors chase favorite players, some build complete sets, some collect sealed wax, and others focus on graded investment pieces. There is no one correct way to collect. The best collection is one you enjoy and understand.

Collector Rule

Buy what you understand, protect what you own, and keep records as your collection grows.

Terms to Know

  • Raw card: A card that has not been graded or encapsulated.
  • Graded card: A card authenticated and assigned a condition grade by a grading company.
  • Rookie card: A player's early officially licensed card, often marked RC.
  • Parallel: A variation of a base card, often with different color, foil, finish, or numbering.
  • Insert: A themed card found outside the standard base set.
  • Auto: A card signed by the player or subject.
  • Relic / memorabilia: A card containing jersey, patch, bat, ball, or event-used material.
  • SP / SSP: Short print or super short print cards with lower availability.
  • Serial numbered: A card stamped with a limited print number, such as 14/25.

Guide 02

Handling Cards Properly

Most avoidable damage happens during handling. Fingerprints, corner dings, surface scratches, and edge wear can all reduce value.

Do

  • Wash and dry your hands before handling cards.
  • Hold cards gently by the left and right edges.
  • Use a clean desk, microfiber mat, or soft card sorting surface.
  • Keep cards away from food, drinks, pets, and direct sunlight.
  • Move slowly when placing cards into sleeves or holders.

Don't

  • Touch chrome, foil, autograph, or dark glossy surfaces.
  • Slide raw cards across tables.
  • Stack raw cards without sleeves.
  • Use rubber bands.
  • Leave cards loose in a box, bag, or vehicle.
Pro Tip: Dark chrome and glossy cards show fingerprints, dimples, roller marks, and print lines more easily than paper cards. Handle them as little as possible.

Guide 03

Penny Sleeves & Top Loaders

A penny sleeve is the first line of protection. A top loader adds rigid protection. Most valuable raw cards should be sleeved before going into any hard holder.

1

Open the Sleeve

Gently pinch the sleeve so the opening separates. Do not jam the card into a closed sleeve.

2

Insert One Corner

Start with one bottom corner, then slowly guide the other side into the sleeve.

3

Slide Slowly

Let the card settle naturally. Avoid pressure on corners or edges.

4

Add a Top Loader

Once sleeved, guide the card into the correct thickness top loader. Never force it.

35 ptStandard base cards, most standard chrome cards, many standard inserts.
55 ptSlightly thicker stock, premium inserts, some numbered cards.
75–100 ptRelics, thicker parallels, many memorabilia cards.
130–180 ptPatch cards, RPAs, thick premium releases, booklet-style cards.
240 pt+Oversized premium memorabilia cards and very thick specialty cards.
Pro Tip: If a card catches or bows when entering a top loader, stop. You likely need a thicker holder.

Guide 04

One-Touch Magnetic Holders

One-Touch holders are excellent for display and higher-end raw cards, but only when the size matches the card. A loose card can shift and damage corners. A tight holder can pinch edges.

Best For

  • Autographs
  • Patch cards
  • Low-numbered cards
  • Display pieces
  • Personal collection cards

Use Carefully

  • Match holder thickness to the card.
  • Check that the card does not slide inside.
  • Do not over-handle magnetic holders around dust or grit.
  • Use a graded-card sleeve or team bag over the case when storing.

Guide 05

Card Savers & Grading Submissions

Semi-rigid card holders are commonly used for grading submissions because cards can be removed by grading staff more safely than from rigid top loaders.

Submission Setup

Fresh sleeve → semi-rigid Card Saver → submission order protection → secure box. Follow the grading company's current instructions before shipping.

Guide 06

Storing Your Collection

Cards age best in stable conditions. Heat, humidity, sunlight, and pressure are the enemy.

TemperatureKeep cards in a cool, stable environment. A good target is roughly 65–72°F.
HumidityAim for a dry, stable space. Many collectors target roughly 35–50% humidity.
LightAvoid direct sunlight. UV exposure can fade autographs, paper, and color.
PositionStore sleeved/top-loaded cards upright in properly sized storage boxes.
LocationAvoid attics, garages, damp basements, and vehicles.
SlabsUse graded-card sleeves to reduce scratching on holders.

Guide 07

Shipping Cards Safely

Proper shipping protects the card, the buyer, and your reputation. The goal is to prevent bending, movement, moisture, and corner impact.

Standard Raw Card

  1. Penny sleeve
  2. Top loader
  3. Team bag
  4. Cardboard sandwich
  5. Bubble mailer

High-End Card

  1. Sleeve or proper holder
  2. Team bag or graded sleeve
  3. Bubble wrap
  4. Small box
  5. Insurance and signature when appropriate
Pro Tip: Never place tape directly on a top loader opening unless the card is already sealed inside a team bag. Painter's tape is safer than clear packing tape.

Guide 08

Preparing Cards for Grading

Grading is not automatically worth it for every card. Consider the card's value, condition, player demand, grading cost, and expected turnaround before submitting.

✓CenteringCompare left/right and top/bottom borders. Centering can heavily affect grade.
✓CornersLook for whitening, bends, dings, soft corners, and visible wear.
✓EdgesCheck chipping, rough cuts, dents, and foil lift.
✓SurfaceInspect under good light for scratches, dimples, fingerprints, print lines, and dents.
Pro Tip: Microfiber cloths are generally for slabs and holders, not aggressive cleaning on raw cards. Never use water, alcohol, glass cleaner, or chemicals on raw cards.

Collector FAQ

Frequently Asked Questions

Should I sleeve every card?

Not every common card needs premium storage, but any card with financial or sentimental value should be sleeved immediately.

Are top loaders better than One-Touch holders?

They serve different purposes. Top loaders are great for storage and shipping. One-Touch holders are excellent for display when the size matches the card.

Should I grade every rookie card?

No. Consider card condition, player demand, grading cost, expected value, and whether a high grade is realistic.

Can I clean fingerprints off raw cards?

Be extremely careful. Do not use liquids or chemicals. When in doubt, leave the card alone rather than risk damage.

What is the safest way to ship a card?

For most raw cards: sleeve, top loader, team bag, cardboard sandwich, and bubble mailer. For high-end cards, use a box, insurance, and signature confirmation when appropriate.

How do I know which top loader size to use?

If a card does not slide in smoothly while sleeved, use a thicker holder. Never force a card into a top loader.
