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 | Large looped initial S, compressed 'ean', a very tall looped second S/C rising well above the line, low small-case 'chemmel' run, ending in a rising looped 'l'. Inscription 'Goku' sits below and right. | Same architecture in R1, R2, R4, R5, R6, R7 and R8. The tall upper loop of the Schemmel capital dominates, with a low trailing surname and a 'Goku' tag below right. R8 is nearly identical in proportions. | Match |
| Slant and baseline | Moderate right slant. Baseline rises gently left to right, and the 'Goku' line drops beneath the surname end. | Right slant with a gently rising baseline in R2, R5, R6 and R8. The R8 baseline angle closely mirrors ours. | Match |
| Letter construction | First S is a large open loop with a long lead-in from lower left. 'ean' is reduced to small humps. The Schemmel capital is a tall narrow loop with its downstroke cutting through the first-name area. 'chemmel' is a series of small arcades. | Same constructions throughout, especially R5, R6 and R8. In R2 and R1 the 'ean' is slightly more legible; that is natural variation. | Match |
| Connecting strokes | First name connects into the surname capital without a lift. The surname runs continuously into the terminal loop. | Continuous connection of 'Sean' into the tall Schemmel loop is seen in R5, R6 and R8. | Match |
| Starting and ending strokes | Starts with a sweeping stroke at lower left into the S. Ends with an upward rightward hook/loop on the final 'l'. Strokes appear tapered rather than blunt. | Same lower-left entry and rising terminal hook in R2, R5, R6 and R8. | Match |
| Line quality and speed | Smooth, confident curves with no visible tremor or hesitation at this resolution. Loops are fluid and the overlaps look naturally executed. | References show fast, fluid execution. R8 shows comparable speed on a similar surface. | Match |
| Pen pressure pattern | Some apparent width variation on the downstrokes of the large loops. Fine marker limits how much this can be read from a scan. | Paint-pen references (R1, R2, R4-R7) show little pressure variation by nature. R8 shows modest variation similar to ours. | Not assessable |
| Spacing | Tight, compressed first name with the surname's small letters closely packed. 'Goku' is spaced beneath the end of the surname. | Consistent compression in R5, R6 and R8. | Match |
| Flourishes and inscription | 'Goku' inscription with a looped G and abbreviated trailing letters. No underline. | A 'Goku' inscription appears in R1, R2, R4, R5, R6, R7 and R8 with the same looped-G abbreviated form. No underline in any reference. | Match |
| Placement and size | Placed across the lower-middle of the card over the text box and art, sized to fit the card width. | R8 is placed similarly over the art and text on a Fusion World card. Funko references are scaled to the box window. | Natural variation |
| Reproduction indicators | No halftone/dot pattern visible. Ink appears to sit on top of the printed text and art, and the overlaps with card text look physical. Ink density appears slightly variable rather than perfectly uniform. | N/A | Not assessable |
Examiner notes
Our card is a 2025 Fusion World Manga Booster 02 (SB02-038), so the signature cannot predate 2025 and is likely a 2025-2026 convention or private signing. R8 (CGC, signer-dated 2/12/26, black ink on a Fusion World card) is the closest match in era and surface. R1, R2 and R4-R7 are Funko Pop box-window signings in paint pen, undated but modern, and show the same stable convention-style form. R3 is a dual-signed card whose Schemmel portion is a more compressed, hurried variant. Differences in loop width and letter legibility across the set fit surface (slick acetate vs. card) and pen (paint pen vs. fine black marker), not era drift.
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.
