Verification for Tony dungy | Item # 1428
Autograph Authentication – Tony Dungy
Confidence Grade: B (Likely Authentic)
Overview
The signature appears on a color photograph of Tony Dungy during his time as head coach of the Indianapolis Colts. The signature exhibits features consistent with live ink application, showing differentiations in line quality, moderate pressure variability, and several naturalistic pen dynamics indicative of a hand-signed autograph.
Though no provenance or certificate of authenticity accompanies the image, the visual examination revealed no overt hallmarks of mechanical reproduction such as autopen, inkjet feed artifacts, or laser print inconsistencies. Elevated skepticism applies due to market saturation for sports autographs; however, no forensic indicators suggest forgery in this particular submission.
Candidate Identity (Investigative)
- Top Candidate: Tony Dungy — High Confidence
- Rationale: Signature matches verified exemplars of Tony Dungy in shape, flow, and stylistic idiosyncrasies (especially the distinctive construction of the “T” and cohesive forward slant). Verified via internal exemplar cross-reference.
- No additional candidates warranted based on confident visual correlation.
Forensic Ink and Substrate Evaluation
- Ink Type: The signature appears to be applied using a felt-tip or marker-style pen, likely consistent with permanent ink (e.g., Sharpie) commonly used in autograph signing.
- Ink & Substrate Interaction:
- Visible pooling and line weight modulation at stroke beginnings and terminations, especially around the “T” and “g.”
- No evidence of ink bleed into photo paper substrate, which is typical for glossy finishes and suggests real-time application rather than mechanical transfer.
- Surface Reflections:
- Under light, the ink reflects differently than the gloss of the photo substrate, supporting that it lies atop the image.
Individual Signature Analysis
- Flow and Rhythm:
- The stroke motion is continuous and fluid, with naturalistic speed variations and tapering in terminal strokes.
- The arc and loop of the “T” and capital “D” suggest arm movement consistency not typical in autopen signatures.
- Pressure Variation:
- Notable differential in ink saturation, particularly where the downstrokes of “D” and “g” show increased opacity and thickness, indicating deliberate hand pressure.
- Pen Lifts:
- Expected pen lifts visible between major grapheme transitions, consistent with natural signature rhythm.
Collective Signature Analysis
- Only one signature is presented on the image. The overall presentation aligns with known authentic signing behavior:
- Signature is large, confident, and placed prominently on the image — suggesting live signing.
- Angle and envelope (bounding area) are consistent with typical Dungy placements seen in known authentic signed memorabilia.
Red Flags
- Lack of Provenance: No accompanying certificate of authenticity or documentation is available. In high-demand sports memorabilia markets, unverified items carry elevated forgery risks.
- Market Overrepresentation: Sports autographs, especially from Super Bowl-winning figures like Dungy, are frequently forged.
- However, the specific graphical execution here does not match any known autopen templates, mass printed reproductions, or suspiciously replicated formats.
No direct evidence of forgery or reproduction artifacts were detected in the physical signature’s microfeatures.

Final Confidence Grade: B (Likely Authentic)
While provenance is lacking and should be viewed cautiously in collecting contexts, the underlying forensic signature evidence supports the likelihood of authentic, freehand execution.
