How can we help?
Guides to buying, selling, card condition and safe trading – all in one place.
Four steps
How KorttiMarket works
Cards change hands directly from one collector to another. We provide the marketplace, fair auction rules and the tools – payment and delivery are agreed with the seller.
Find a card
Search by name, set or number and filter by condition, language, grading and price.
Bid or buy now
Place a maximum bid and the system raises your bid only as much as needed. With a Buy Now price the deal is done instantly.
Pay the seller
Agree on payment and delivery with the seller. Only pay to the account or number the seller has given.
Leave feedback
Once the cards arrive, give the seller 1–5 stars. Feedback builds trust for everyone.
Fair finish
No last-second surprises
If a price-changing bid arrives with less than 2 minutes left, the auction end moves to 2 minutes after that bid. Everyone gets a chance to respond.

What is KorttiMarket?
KorttiMarket is a Finnish online marketplace for trading cards where private persons and businesses buy and sell cards by auction or at a fixed price. The Service includes Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece and Lorcana cards as well as hockey cards. Read more: About KorttiMarket.
Is KorttiMarket free to use?
Yes, buying is free and selling is currently free for private sellers. If fees are introduced, they will be shown clearly before you publish a listing. See Fees.
How does an auction work?
In an auction, the buyer with the highest bid wins when the auction ends. The listing shows the current price, the time left and the lowest acceptable next bid. Bidding requires a logged-in account with a verified email address. See How buying works.
How do I pay for the cards?
You pay the seller directly in the agreed way, for example by bank transfer, MobilePay or cash on pickup. Pay only to the account or number the seller gave and only to whoever is selling the card. See Safe trading.
How do I sell a card?
Create a listing on the Sell page: choose the category and card details, add photos, state the condition, set a price and choose auction or Buy Now. Good photos and an honest description sell best. See How selling works.
What do the condition grades mean?
The condition grades are Mint (flawless), Near Mint (almost flawless), Excellent, Good, Light Played, Played and Poor, and they describe wear on corners, edges and surface as well as creases. A Near Mint card, for example, may have at most very small marks but no creases. See Condition guide.
How do I report a suspicious listing?
Use the Report function on the listing or user, or write to [email protected] and include a link and reasons. We handle reports and tell you the decision. Instructions: Report content.
How do I delete my account and data?
You can delete your account and download your data directly in Account settings. Deleting the account does not release you from obligations arising from sales already made. More information: Privacy policy.
