What Magic collectors say

Real experiences from Magic players and collectors across Europe who sold their cards to Big O Cards.

„Great support starting from a lightning-fast quote with an unmatched percentage rate, followed by shipping instructions (fully paid for by the store—and I sent 4 packages from Poland, over 900 km away!). Fast evaluation of the delivered cards—over 11,000 processed in just a few hours. The final offer was even better than expected. A responsible and accommodating store!“

Mateusz Stepien (Poland)
  • I recently sold 6 duals and the experience was perfect from A to Z. They appraised the cards I had fairly, offered a decent amount of money for them, explained the transaction procedure in detail and helped me with process of sending them from the Netherlands to Germany. The communication was fast, smooth and pleasant. I can recommend this business to everyone!

    Xandriana N. (Netherlands)

  • I sold a large collection (worth around 2000€) to Oliver and was completely satisfied with the support throughout the process. All agreements were honored, and the payment was made promptly after a brief inspection. Communication was friendly and professional.

Frequently asked questions

See all questions
How secure is selling my cards? (Contract & Shipping)

Your security is our priority. For collections valued at 1,000€ or more, we are happy to provide a written purchase agreement upon request – giving you maximum legal certainty before you ship your collection.

 You will always receive a tracking number, and your package is insured via DHL for at least 500€. Additionally, we transparently document the arrival and verification of your cards.

Secure transport for especially valuable shipments: High-value collections are picked up by an insured courier, fully insured even for several thousand euros, anywhere in Europe.

Do I have to pay for shipping?

We make it easy: From a value of 300€, we provide a free DHL label for sellers in Germany. For collections sent from Austria or the rest of the EU, we offer attractive shipping solutions and support.
Most importantly: If you decide not to accept our final offer, we will return your cards to you free of charge. You take absolutely zero risk.

Do you buy Magic cards in Hamburg (Germany)?

Yes! Although we operate as an online dealer across Europe, our headquarters are in Hamburg, Germany.  If you want to sell Magic cards in Hamburg, we offer in-person handovers for high-value collections by appointment. For all other customers, we offer secure, insured shipping.

Why should I sell my Magic collection to a card dealer?

If you want to sell a Magic collection, you face a choice: selling singles on platforms or using an MTG dealer buy-list. Selling to Big O Cards saves you hundreds of hours of work. We professionally evaluate your collection, whether it’s Vintage, Legacy, Modern, or Commander. Instead of listing, grading, and shipping every single card, you receive an instant payout for your entire lot.

Which Magic cards are valuable and what do you buy?

We buy almost everything – from High-End rarities (Power Nine, Dual Lands) to massive collections with thousands of Commons/Uncommons (Bulk). We don’t just cherry-pick the best cards; we buy the entire collection. This ensures you aren't left with the bulk.

How does card condition grading work?

We grade fairly according to European standards (Cardmarket). We don't use a microscope to find micro-scratches just to lower the price; we grade as if we were buying or selling the card ourselves. If you disagree with our assessment, our 0% Risk Guarantee applies: We will return your cards free of charge.

Why Big O Cards?

A small team from Hamburg who collect Magic themselves.

Having collected Magic cards for years ourselves, we built Big O Cards to provide the service we always wished for when selling Magic cards.

Listing every card on a marketplace is time-consuming and risky; local game stores often pay only 40–60 % of market value. We pay around 70–75 %, with a fast transaction and the highest security standards.
