How to describe signed or altered Magic cards on Cardmarket

To list a signed or altered Magic card, identify its exact printing and physical condition first. Then declare the modification in the appropriate fields and show photographs of the real copy. A signature or art extension does not automatically improve its condition or value.

Signature, alteration and condition are separate facts

Cardmarket has structured fields for card name, set, language, condition, foil, signature and alteration. A comment must not contradict those fields. A Near Mint card does not become Mint because it is signed, nor does an art extension erase existing wear.

Cardmarket's condition guide is specific about “signed”: it covers the artist's signature or Richard Garfield's and a few closely connected cases. Do not automatically mark an unrelated autograph as “signed”; the platform says a signature outside its criteria may require a Poor listing. Check the current rule for your card before posting.

Prepare a verifiable listing

Identify set, collector number, language and finish. Added artwork does not replace the original printing's identity.
Select “signed” or “altered” only where Cardmarket's rules apply; do not hide the modification in a standard listing's comment.
Photograph the whole front, the back, a close-up of the signature or paint and any wear. Cardmarket requires an image for altered cards.
State who signed it if you can document that, where the signature sits, what was painted and whether text or symbols are covered.
Judge edges, corners, surface and back separately. If one side is notably worse, use the conservative condition supported by the platform's rules.

For example: “Set X, no. Y, English, foil; artist signature near lower border; whitening on back corner; both sides photographed.” That gives a buyer more than “signed NM bargain.” A signature's authenticity may need separate evidence; checking the “signed” box is not independent certification.

Price and buyer use

Compare completed sales of the same printing and kind of modification. Some collectors seek a particular signature; others prefer an untouched card. For organized play, ask the event whether an alter is acceptable: marketplace classification and tournament approval answer different questions.

Frequently asked questions

Is a signed Magic card worth more?

It depends on the signer, card, authenticity and demand. Do not assume a fixed premium without comparable completed sales.

Can I list an altered card without a photo?

Cardmarket says altered cards should only be offered alongside an image of the modified card. Show the back and relevant defects too.

Two separate questions about a modification

“How should I list it?” uses Cardmarket’s criteria. “May I play it at this tournament?” requires the organizer and event policy. A listing checkbox does not authorize tournament use. Photograph the modification and record who signed or altered it without inventing authentication.

If a signature covers part of the name, describe what is hidden and seek guidance before registering the deck. Do not add ink to restore text or erase a signature to improve the stated condition.
