How to trade cards in person and online

Checking a card trade starts with three checks on both sides: the same price source for every card on the same day, one condition scale, and a cert lookup for every slab. In person, you check the cards in hand before anything changes hands. By mail, both people ship, so each package needs tracking and insurance for the full value of what is inside. A swap has no checkout, so marketplace protections don’t attach to it: Whatnot, for one, says it can’t support transactions made outside its platform.

Where can you trade cards?

A shop trade-in works like a sale: the shop buys your cards at its own rates and pays in credit or cash. In TCGplayer’s buylist system, a shop sets a cash percentage and a store credit percentage separately, and TCGplayer advises giving a little more in credit. Our guide to selling cards to a local shop shows some posted rates.

Shows are built for trading face to face. The 2026 National Sports Collectors Convention in Rosemont, Illinois, ran a Trade Night from 6 pm to 11 pm on Thursday, Friday and Saturday, July 30 to August 1, and its page invited visitors to bring cards to trade or sell. Our guide to your first card show covers how a show works.

A rip site’s instant trade-in offer is a different thing again: the site buys back a card you got from a pack. Our guide on how to judge a trade-in offer covers those.

How do you value both sides of a trade?

Use one method for every card on both sides, on the same day.

1. Identify each card exactly. The set, the card number, the printing and the language, and for a slab, the grader and the grade. Two printings of one card can sell far apart.
2. Use sold prices, from one source. Listed prices are only asks. TCGplayer’s Market Price, for one, is worked out from recent sales on its own platform. Our guides on how to find what a card sold for and market, listed and sold prices explain the difference. For English Pokémon cards, Rip.fan’s card price lookup gives a dated NM market price, and the trade checker lists both sides with each card’s price, the two totals and the difference.
3. Price each card at its real condition or grade. A Lightly Played copy is not a Near Mint copy, and a 9 is not a 10.
4. Write down both totals and the gap in dollars. Settle the gap before anyone hands over or ships a card, by adding a card or changing the mix.

A short trade sheet keeps both people honest. Make one line per card:

If one side priced from listings and the other from sales, redo both sides from the same source.

How do you check condition on both sides?

Agree on one scale. The marketplaces use different ones. TCGplayer has five steps, from Near Mint down to Damaged. eBay has four labels for an ungraded card, topped by Near Mint or Better. Whatnot also has four: Near Mint, Good and Damaged, plus a top step above Near Mint for cards with no visible wear, and by its own description its Near Mint also takes in cards a shop would grade one step lower. So name the scale in the deal, such as “NM on TCGplayer’s scale”. Our guide to card condition grades sets out what each step allows.

In person, look at each raw card under a bright light, then tilt it so the light runs across the surface, and check the back, the corners and the edges. Our centering checker turns four border widths you measure into left-and-right and top-and-bottom splits.

By mail, ask for photos of each card’s front and back, plus close-ups of the corners and any flaw. On a slab, the label should be readable.

For every slab, look up the cert number yourself on the grader’s own site. CGC images every card after sealing it and shows those images in its Verify CGC Certification tool, so you can compare CGC’s photo with the card you are offered. Our guides to spotting a fake slab and spotting fake Pokémon cards cover the checks for a card that looks wrong.

How should you ship a trade both ways?

1. Agree in writing. List the cards going each way, their conditions, the shipping service, the insurance and the day you will both ship. Keep the messages.
2. Ship on the same day, with matching service, and swap tracking numbers.
3. Pack for the value. Our guides to shipping raw cards and shipping a graded card cover sleeves, toploaders, boxes and padding.
4. Record the packing. Whatnot strongly recommends that sellers of high-value orders film themselves packing and shipping, and the same habit protects a trade.

USPS prices, from its price list effective October 4, 2026. USPS bases the insurance fee on the item’s declared value, so declare the full value of what is inside each package.

A Certificate of Mailing suits a low-value trade in a plain envelope: it is an official record of the date USPS took the item, though it is no tracking. USPS keeps no copy, so hold on to it.

What happens if a trade goes wrong?

Don’t count on a marketplace. A swap has no checkout for buyer protection to attach to. Whatnot tells users to keep buying, selling and payments on Whatnot, to report anyone who asks to move a deal elsewhere, and says it can’t support transactions outside the platform. Its Buyer Protection excludes them. TCGplayer’s seller agreement bars sellers from steering buyers to complete a transaction elsewhere. A swap you set up through a marketplace’s messages still happens outside that marketplace.

Insurance pays actual value, with proof. USPS pays an insured item’s actual value when mailed, not more. For a collectible, its claim rules ask for proof of that value: a written valuation from a reputable dealer (a licensed business owner qualified to price the item), or the original receipt, invoice or bill of sale. A swap produces no sales receipt of its own, so before you mail a valuable card, ask USPS what it will accept, and keep the trade sheet and the sold prices you used. A claim for damage or missing contents must be filed within 60 days of mailing, and the person who received it must keep the box and packing. A lost insured package can be claimed from 15 days after mailing and no later than 60.

So match the method to the cards. For a card worth more than you can comfortably insure and document, trade in person, at a shop counter, a show or a meetup, where both sides see the cards before anything changes hands. Selling instead of trading? Our guides on how to sell a card collection and where to sell cards online cover the marketplaces.

Frequently asked questions

Can you set up a trade through Whatnot messages?

No. Whatnot bars sharing phone numbers, email addresses or social media handles to move a deal elsewhere, may review messages, and can suspend or ban accounts that take part in off-platform deals.

Can you arrange a trade through eBay messages?

No. Dealing outside eBay breaks its rules, and eBay charges a seller a final value fee, even if nothing sells, for offering contact details or asking for a buyer's to deal outside eBay, figured on the listing price or the price the two agreed, whichever is higher.

What should a CGC slab's label show?

The card's description, grade, certification number and a QR code, sealed in a clear holder with security features against counterfeiting and tampering. CGC also keeps its graders from knowing who sent a card, and rejects any card of questionable authenticity before grading.

Can you trade your own graded cards to a rip site?

At Rips by Triumph, yes, in person: Triumph buys graded cards at card shows and other collector events for store credit in its app. That credit buys only products there, never expires and carries no fees.
