2024 SMZ Comics Metal Trading Card - Artist Auto - Eddie Nuñez · #ø

Authenticated Crown Grading · reviewed Oct 31, 2026

Findings

Signer
Eddie Nuñez
Autograph
Signed directly on the card, front side
Handwriting
Matches the known signatures it was compared with. (6 known signatures)
Printed or copied?
The white ink shows natural density variation, tapered terminals, and slight edge drag. It appears to sit over the printed artwork rather than being part of it. No dot or halftone structure is visible in the crop. Image resolution and the slab glare do not allow confirmation that the ink sits above the card's surface coating, so this needs physical inspection.
Decision
Authenticated by Crown Grading after staff review.

Examiner notes

All material is from the same period. Our card is a 2024 SMZ Comics metal card, and every reference is an SMZ metal-card artist auto from roughly 2023–2025. Era drift is not a factor. The visible differences fall within ordinary signing-to-signing variation and are mostly a matter of how many letters after 'Nu' are written out. Surface and pen are the same type across the set: paint or metallic marker on a glossy metal card.

  • No forgery indicators visible at this resolution. No tremor, blunt stops, odd pen lifts, or halftone pattern.
  • Independence caveat: R4, R5 and R6 are prior Crown authentications with certs 000059929, 000059930 and 000059935. Ours is 000059925, so they are very likely from the same submission batch. They are not independent provenance for this card.
  • There are no witnessed-signing or third-party (PSA/JSA/Beckett) references in the pool.

How Crown authenticates autographs: the signature is compared with known examples gathered from Crown's own authenticated cards, independent authenticators and public listings, measured by software, examined by an AI forensic model, and signed off by Crown Grading staff. The decision above is Crown's.
