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 | Abbreviated two-cluster signature: an angular zigzag 'M' cluster, a gap, then a 'P' with a descending loop and a horizontal 't'-like crossing stroke at the end. | R1, R3, R5 and R6 show the identical two-cluster structure with similar width-to-height ratio. R2, R4, R7 and R8 show the same scheme in black ink. | Match |
| Slant and baseline | Strong rightward slant on the opening 'M' strokes. The baseline runs along the card's long edge because the signature is written vertically. | Rightward slant on the 'M' is seen in all references. Baselines run horizontally on the references, as they are cropped from different card orientations. | Natural variation |
| Letter construction | 'M' is made of rapid sawtooth up-down strokes with a short trailing hook. 'P' is a tall upright stroke with a bowl and a lower loop or descender. | R1 and R6 show the same sawtooth 'M' and the upright 'P' with descender loop. R3 and R5 are near-identical in construction. | Match |
| Connecting strokes | 'M' cluster is written in one continuous motion. There is a pen lift before the 'P' section. | The same lift between the clusters appears consistently in R1–R8. | Match |
| Starting and ending strokes | Starts with a quick entry upstroke into the 'M'. Ends with a long horizontal terminal stroke extending past the 'P' cluster. | R1 and R6 show the same long horizontal terminal. Shorter terminals in R4 and R7 fall within normal variation. | Match |
| Line quality and speed | Fluid, confident strokes with tapered ends and some thinning on fast strokes. No visible tremor or hesitation at this resolution. | References show similarly fast, fluent execution. | Match |
| Pen pressure pattern | Heavier on the downstrokes of the 'M' and the 'P' stem, lighter on connectors. Some ink-density variation is visible. | Similar pressure pattern in R1 and R6 (blue ink) and in the black-ink references. | Match |
| Spacing | Moderate gap between the 'M' and 'P' clusters. | Comparable spacing across the references. | Match |
| Flourishes and underlines | None beyond the terminal horizontal stroke. | None in the references. | Match |
| Placement and size | Blue ink, written vertically along the right side of the sticker over the artwork and red background. Size is proportionate to the card. | Placement varies across references (horizontal on different backgrounds). Blue ink matches R1, R3 and R6. | Natural variation |
Examiner notes
Our card is a 2024 Mutagen Canister Kids open-edition artist auto, the same modern sticker-card period as the Nintendopes references (R2–R8) and the Horrorible Kids Series 9 card (R1). No era-driven change is expected, and none is seen. All references show the same compact two-part 'M ... P/t' abbreviated signature.
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.
