Signature comparison
This card. The signature as cropped from the slab photo (front).
Below, the known examples Crown compared it with. Examples with stronger proof (signed in front of staff, or certified by an independent authenticator) carry the most weight.
Feature by feature
| Feature | This card | Known examples | Result |
|---|---|---|---|
| Overall form and proportions | Compact 'M-c P-t' abbreviated form. Large angular M is followed by a small connected loop, a tall P with a looped bowl, and a trailing t with crossbar. The signature is written vertically along the right edge (rotated relative to the crop). | R1, R2, R3, R4, R6, R7 and R8 show the same abbreviated 'M-c P-t' structure, with a dominant opening M, a short middle element, a tall P and a closing t-cross. R5 is a partial, more stylized crop. | Match |
| Slant and baseline | Rightward slant relative to the signing direction. Baseline rises slightly, with the P and t elements rising above the M. | References show a right slant with a mildly rising or level baseline. R4 and R8 rise similarly. | Natural variation |
| Letter construction | M made with rapid angular peaks and a tail that flows into a small c-like loop. P is a tall downstroke with a bowl. t has a long horizontal crossbar. | Same construction in R2, R6 and R7. R6 in particular shows the same angular M and loop-to-P transition. The t crossbar matches R1, R3 and R7. | Match |
| Connecting strokes | M connects to the following loop; there is a break before P; P connects into the t area. | Same break pattern between the first-name and surname elements in R1, R2, R3, R6, R7 and R8. | Match |
| Starting and ending strokes | Starts with a quick entry stroke into the M. Ends with an outward-flicked t-crossbar. No blunt starts visible at this resolution. | Tapered entry into the M and a flicked ending crossbar across the references. | Match |
| Line quality and speed | Fluent, confident strokes with natural width variation consistent with a marker. No visible tremor or hesitation. | Fast, fluent marker strokes in all references. | Match |
| Pen pressure pattern | Heavier saturation in the M and P downstrokes, lighter in connectors. Ink tone shifts from near-black to blue/green toward one end. | Similar heavy downstrokes. References use a single ink color each (blue or black). | Natural variation |
| Spacing | Moderate gap between the M-group and the P-group. | Comparable spacing in R1, R3, R6 and R7. | Match |
| Flourishes and underlines | None beyond the extended t-crossbar. | No underlines; extended terminal crossbar is typical. | Match |
| Placement and size | Vertical along the right margin over the artwork, medium size. | References are placed over artwork at varying positions. Placement varies by card and is not a strong discriminator. | Natural variation |
| Reproduction indicators | No halftone or dot pattern visible. Ink appears to sit over the printed artwork. Stroke width varies naturally. | N/A | Not assessable |
Examiner notes
Our card is a 2024 Mutagen Canister Kids Stickers Open Edition artist auto. All references come from the same artist-issued Magic Marker Art / Nintendopes / Horrorible Kids sticker-card releases of roughly the same recent period, so there is no meaningful era gap. Differences are best explained by marker type, card surface (glossy vs. matte color fields) and signing speed.
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.
