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 | Small '4'/Y-like lead mark, then a large open U-shaped capital. 'ODIE' is set small and on a diagonal inside it, then 'WA' with a large right-hand oval, a small 'Y/5' at upper right, and a long diagonal underline. Height-to-width is 0.819. | Every reference shows the same layout: lead mark, large U capital, diagonal small 'ODIE', 'WA' plus large oval, top-right terminal mark and diagonal underline. Measured height-to-width runs 0.747 to 0.889. | Match |
| Slant and baseline | Upright strokes lean left at -10.6°. The 'ODIE' and 'WA' blocks climb diagonally up and to the right. | Slant runs -11.0 to -0.7°, average -6.83°. The same rising diagonal of the inner letters appears in R1-R8. | Natural variation |
| Letter construction | The capital opens with a small hooked 'a'/c-like entry before the U. 'O-D-I-E' are small separated print forms. 'W' is angular, with 'A' or a 4-like form next to it. | Entry forms vary across the set: R1 and R3 use a tight hook, while R2, R6 and R7 use an open '4'. Inner letters are built the same small, disconnected way throughout. | Natural variation |
| Connecting strokes | Mostly disconnected print. The large ovals enclose the inner letters rather than joining them. | Same disconnected, enclosing structure in all references. | Match |
| Starting and ending strokes | The underline starts lower left and finishes in a tapered upper-right exit. The top-right terminal mark is a small quick figure. | Underlines taper the same way (R1, R3, R4). The top-right terminal mark varies from a 'Y' to a small 'v' or '5' shape. | Match |
| Line quality and speed | Large ovals look fluid and continuous, with no visible tremor or hesitation at this resolution. Strokes taper rather than ending bluntly. | Fluid, fast ovals with tapered ends in R1-R4. | Match |
| Pen pressure pattern | Thickness varies modestly along the strokes (0.435, photo-sensitive). | Thickness variation 0.436 to 0.483 across the measured references. | Match |
| Spacing | Inner letters are tightly packed inside the large loops. 'WA' sits just below 'ODIE'. | Same tight internal spacing; R5-R8 are slightly more compressed. | Natural variation |
| Flourishes and underlines | One long diagonal underline. | Single underline in R1, R3 and R4. Double or multiple underline strokes in R2, R6 and R8. | Natural variation |
| Placement and size | Lower right of the card, over the fur belt, blue pants and lightning, ending above the flames. It takes up roughly a third of the card width. | The same placement zone and similar size in every reference. | Match |
| Reproduction indicators | Our signature differs in detail from each reference (entry hook, terminal mark, underline count). No halftone pattern is visible in the ink at this resolution. | References also differ from one another, as hand-signed copies of the same card would. | Not assessable |
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 | -10.6° | -11.0–-0.7° | In range | |
| Height to width | 0.819 | 0.747–0.889 | In range | |
| Ink travel per unit width | 5.22× | 5.18–5.73× | In range | |
| Stroke thickness variation | 0.435 | 0.436–0.483 | In range | |
| Closed loops | 2 | 1.0–4.0 | In range | |
| Separate strokes | 14 | 10.0–15.0 | In range |
The two measurements that count toward the decision are the lean of the upright strokes and the signature's height-to-width shape. Ours leans -10.6°, against references ranging from -11.0° to -0.7°. Its height-to-width ratio is 0.819, almost exactly the reference average of 0.81. Both sit comfortably within how much YodieWay's own signatures vary. The photo-sensitive figures (ink travel, stroke thickness variation, closed loops and separate strokes) also fall within the reference range, though they are not used in the call. Taken together, the numbers support authenticating this signature, but they confirm shape and proportion only and cannot by themselves prove live ink.
Examiner notes
Our card is the 2026 WhatNot Streamer YodieWay - Auto #0, serial 000062467. All eight references are the same card design, Crown-authenticated, with serials 000050495 to 000065297, so they come from the same short signing period as ours. Era drift is not a factor, and the references directly show this signer's range on this exact surface and placement. The references do not state whether the signings were staff-witnessed, so they are weighted as Crown-reviewed references rather than witnessed provenance.
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.
