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 'Cole' (hooked C, tall looped l, small e) followed by an abbreviated 'Turner' with a dominant T and a compressed, wavy 'urner' tail. | The same two-part structure appears in R1–R8: a short hooked C, tall l loop, small e, a large T and a compressed wavy remainder. | Match |
| Slant and baseline | Moderate right-leaning uprights. The baseline rises slightly to the right. | Similar lean throughout. Baselines run from flat to slightly rising (R2, R6, R8). | Natural variation |
| Letter construction | C is a short open hook. The l is a tall narrow loop and the e a small closed eye. The T is built as a Z-like down-stroke joined to a long crossbar. 'urner' is reduced to rounded humps ending in a small loop. | The same Z-like T construction and reduced 'urner' appear in R2, R3, R4, R5, R6 and R8. R1 and R7 show the same forms, though the images are fragmented. | Match |
| Connecting strokes | 'Cole' is written fluidly with a joined l–e. The T crossbar is a separate sweep. 'urner' is largely continuous. | Same connection pattern, with the crossbar as a separate or partly joined sweep, in R2, R4, R5 and R8. | Match |
| Starting and ending strokes | Quick tapered entry on the C. 'Turner' ends in a small curl or hook at the right. | Tapered C entry and a small terminal hook or curl are seen across references (R2, R4, R6, R8). | Match |
| Line quality and speed | Smooth, confident curves with no visible tremor, hesitation or blunt stops at this resolution. | All references show fast, fluent strokes of comparable quality. | Match |
| Pen pressure pattern | Slightly heavier on down-strokes and lighter on the upper crossbar sweep, in blue felt/paint-type ink. | Similar pressure modulation in R2, R5 and R8. The pen type looks comparable. | Natural variation |
| Spacing | Clear gap between 'Cole' and 'Turner'. 'Turner' is tightly compressed. | Comparable inter-word gap and compressed surname. | Match |
| Flourishes | A long T crossbar rises to the right and arcs over the rest of the surname. | The long rising crossbar is a hallmark in R1, R2, R4, R5, R6 and R8. It is shorter in R3 and R7. | Match |
| Placement and size | Signed in the lower clear/patterned autograph window of a Wild Card Matte Premium card, spanning most of the window width. | R2, the same Wild Card Matte product, shows the same patterned background and similar sizing within the window. | Match |
Measurements
Software traced the ink and measured it against the known examples. The shaded band is the signer's normal range across those examples; the gold marker is this card.
| Feature | This card | Known examples | Normal range | |
|---|---|---|---|---|
| Slant of upright strokes | -11.8° | -14.8–-5.8° | In range | |
| Overall writing angle | 4.4° | -2.1–2.2° | In range | |
| Height to width | 0.378 | 0.239–0.399 | In range | |
| Ink travel per unit width | 4.09× | 3.19–4.7× | In range | |
| Stroke thickness variation | 0.382 | 0.339–0.378 | In range | |
| Closed loops | 5 | 0.0–7.0 | In range | |
| Separate strokes | 5 | 3.0–21.0 | In range |
Our software measured this signature against six clean reference signatures from Cole Turner's 2022 autograph cards. The main shape measures all sit well within his normal range: slant of the upright strokes, overall writing angle, and height relative to width. Ink travel, stroke thickness variation, closed loops and number of separate strokes also fall within his range, though those are more affected by photo quality and pen type. Every measurement came out normal and none was flagged. The numbers support the visual finding that this signature fits how Cole Turner signed in 2022.
Examiner notes
Our card is a 2022 Wild Card Matte Premium Autograph, signed in Cole Turner's pre-draft and rookie period. All eight references are 2022 manufacturer autograph releases (Leaf Pro Set Draft, Wild Card Matte, Leaf Draft, SAGE High Series, Leaf Flash). Era is effectively identical, so there is no career drift to explain. The remaining variation comes down to pen, surface 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.
