About Big O Cards
Selling Magic cards should be simple, fair and safe. That is why we exist.
Why we exist
Having made a lot of experiences in the trading card segment as players and collectors ourselves, we dedicated Big O Cards to providing the service we always wished for when selling Magic cards.
Selling singles on platforms: Listing each card individually and shipping to numerous buyers is time-consuming and often results in fraud and stress.
Local game stores: Practically no risk, but offered prices are between 40 and 60 % of fair market value. With Dual Lands, that really hurts.
Big O Cards: Around 70–75 % of fair market value, a fast transaction and the highest security standards.
Why Big O Cards?
Not an anonymous corporation, but a team from Hamburg.
Having collected and played 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.

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!“
Super easy process. Took photos of my cards, received an offer, sent cards, quickly checked and got the money. (Price not bad either ;)

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.

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!
