1. Where to Sell Your Cards

Not all selling platforms are created equal. Here's a ranked breakdown by ease of use and buyer safety, from best to most risky.

TCGPlayer

Best for Singles

The biggest marketplace for individual Pokemon cards. Huge buyer base, verified sellers, and built-in buyer protection. You set your own price and TCGPlayer handles disputes. Fees run around 10-12%, which is reasonable for the volume of traffic you get.

eBay

Great for graded cards and sealed product. You can list as auction or Buy It Now. Fees are around 13%. Use eBay's promoted listings feature to boost visibility on high-value items. eBay's audience is massive, so rare cards tend to get competitive bidding.

Facebook Groups

Pokemon TCG Buy/Sell/Trade groups are very active and have no platform fees. The tradeoff is higher scam risk. Always use PayPal Goods & Services for transactions. Never use Friends & Family, Venmo, or Cash App. If a buyer insists on skipping PayPal G&S, walk away.

Local Game Stores

Instant cash, but they'll typically pay 40-60% of market value. They need to make a margin when they resell. Best option if you have bulk commons/uncommons to unload or you need money fast. Don't expect top dollar.

2. How to Price Your Cards

Pricing is where most new sellers mess up. Don't guess. Don't use the price on a random listing you found. Use actual data.

Pricing Steps

  1. 1Check TCGPlayer market price. This is your baseline. It reflects what the card is actually selling for, not what people are hoping to get.
  2. 2Check eBay sold listings. Not active listings. Sold listings. Filter by "Sold Items" to see what buyers actually paid. Active listings just show what sellers are asking, which is often inflated.
  3. 3Factor in condition. NM (Near Mint) gets full market price. LP (Lightly Played) is about 80-85%. MP (Moderately Played) is 60-70%. HP (Heavily Played) is 40-50%.

Graded cards have separate pricing. A PSA 10 can sell for 2-10x the raw Near Mint price depending on the card. Use the collection tracker to see current market prices for your cards.

3. Card Condition Grading

Condition is everything when selling cards. Be honest about it. Overgrading your cards kills your reputation faster than anything else. Here's what each grade actually means in plain English.

NM

Near Mint

Looks like it just came out of a pack. No edge whitening, no scratches, no wear. Hold it under bright light and tilt it around. If you can't find a flaw, it's NM.

LP

Lightly Played

Minor edge whitening or very faint surface scratches. You have to look closely to notice the wear. Still looks great in a binder or sleeve. Most played cards in good condition land here.

MP

Moderately Played

Noticeable wear that you can see without squinting. Small creases, visible edge whitening, surface scratches. Still playable in a sleeve, but not one you'd put in a display case.

HP

Heavily Played

Heavy wear, creases, significant whitening on edges and corners. This card has seen a lot of play or poor storage. Still has value for players who just want the card for their deck.

DMG

Damaged

Bends, tears, water damage, major creases. The card is structurally compromised. Still worth listing if it's a rare card, but price accordingly and photograph every flaw.

Be honest about condition. Listing a LP card as NM will get you returns, negative reviews, and potential account strikes. When in doubt, grade one step lower than you think. Buyers love getting a card that's better than described.

4. How to Ship Cards Safely

Bad shipping is the fastest way to lose money and reputation. A card that arrives damaged is a refund, a negative review, and a lost customer. Follow these steps every single time.

Shipping Step by Step

  1. 1Sleeve the card. Penny sleeve at minimum. This prevents the card from shifting and scratching against the top loader.
  2. 2Put it in a top loader. The top loader provides rigid protection so the card can't bend in transit.
  3. 3Tape the top of the top loader. A small piece of tape across the opening so the card can't slide out. Don't put tape on the card itself.
  4. 4Wrap in a team bag or piece of paper. This adds a moisture barrier and keeps everything snug inside the mailer.
  5. 5Place in a bubble mailer. Never ship in a plain envelope. Plain envelopes get crushed, bent, and run through sorting machines that will destroy the card.
  6. 6Add tracking. Always. No exceptions. Tracking protects you from "I never received it" claims.

Value thresholds: For cards over $20, always use a padded mailer with tracking. For cards over $50, consider adding shipping insurance. The cost of insurance is tiny compared to eating a lost package.

5. Scam Prevention

Scams are real in the Pokemon card market. The good news is they're pretty easy to spot if you know what to look for.

Red Flags

  • Buyer wants to pay via Venmo, Cash App, or Zelle. These platforms have zero buyer protection. If you send the card and they dispute the payment, you lose both the card and the money.
  • Buyer offers way over asking price. If your card is listed at $50 and someone offers $80, something is wrong. This is usually a setup for an overpayment scam.
  • Buyer wants you to ship before payment clears. Always wait for payment to fully clear before shipping anything. Pending payments can be reversed.
  • New Facebook accounts with no history. Brand new profiles reaching out about high-value cards are almost always scam accounts.
  • Refuses to use PayPal Goods & Services. G&S has a small fee, but it protects both buyer and seller. Anyone who refuses it is trying to avoid accountability.

The golden rule: If something feels off, trust your gut. No single sale is worth getting scammed over. Walk away and sell to someone else.

6. When to Sell Raw vs. Graded

Not every card is worth sending off to PSA or CGC. Grading costs $20-150 per card depending on the service level, plus shipping both ways, plus weeks or months of wait time. The math has to make sense.

Only Grade If All Three Apply

  • The card is NM or better. Sending a LP or MP card for grading is throwing money away. You need to realistically expect a PSA 9 or 10.
  • The card is worth $50+ raw. If the raw card is worth $10, even a PSA 10 probably won't cover grading costs plus your time.
  • A PSA 9 or 10 significantly increases the value. Check eBay sold listings for the graded version. If a PSA 10 sells for 3x raw, the grading fee is worth it.

For most cards, selling raw is more profitable after factoring in grading costs, shipping to the grading company, and wait time. Check out the full grading guide for a deeper breakdown.

7. Trading In Person

Card shows, league nights, and local tournaments are great places to trade. You can inspect cards in person, negotiate face to face, and walk away with exactly what you want. Here's how to do it right.

In-Person Trading Checklist

  • Check condition in person before agreeing. Hold the card under good light. Look at the edges, corners, and surface. Don't rely on the other person's assessment.
  • Use a playmat as a clean surface. Never put cards directly on a table. Tables at card shops and events can have dirt, moisture, or sticky residue.
  • Photograph both sides of valuable cards before trading. This protects you if there's a dispute later about what condition the card was in.
  • Know your prices. Pull up TCGPlayer on your phone before agreeing to any trade. Don't guess at values.

Use the Professor's Research trade system to manage your trades digitally. Track what you're looking for, what you have available, and keep a record of completed trades.

8. Tax Considerations

This part isn't fun, but it matters. If you sell more than $600 in a calendar year on a single platform (eBay, TCGPlayer, etc.), you'll receive a 1099-K tax form. That means the IRS knows about your sales.

What You Need to Know

  • Track your cost basis. Keep records of what you paid for cards (pack price, purchase receipts, trade values). You only owe tax on profit, not gross sales.
  • Save receipts and screenshots. If you bought a card for $30 and sold it for $50, your taxable gain is $20. But you need proof of that $30 purchase.
  • Shipping and supply costs are deductible. Top loaders, bubble mailers, postage. These are business expenses that reduce your taxable profit.

This is not tax advice. If you're selling significant amounts of cards, talk to a tax professional. The rules can vary by state, and a CPA can help you set up proper record-keeping from the start.

9. Shipping Supply Checklist

Stock up on these before you start selling. Running out of top loaders mid-order is no fun. All links below go to Amazon.
