Autograph Authentication – Chase Utley

Confidence Grade: B (Likely Authentic)

---

Overview

This autograph, attributed to former MLB player Chase Utley, appears prominently on a glossy photographic surface. Initial macroscopic inspection reveals characteristics consistent with freehand marker signatures, though there are subtle irregularities worth noting. Based on a forensic inspection of line quality, ink behavior, and micro-level stroke analysis, no clear indicators of autopen or mechanical printing were found. However, due to the absence of provenance and subtle uniformities in pressure distribution, this signature receives a high B grade rather than the highest confidence tier.

Candidate Identity (Investigative):
This item was attributed to Chase Utley. Internal signature comparatives confirm a medium-to-high visual similarity to known Utley exemplars.

• Candidate 1: Chase Utley – High Confidence
  Signature structure and initial “C”/”U” looping consistent with authenticated live-signed examples, particularly on glossy photo media.
• No alternative candidates needed due to match confidence.

Forensic Ink and Substrate Evaluation

• Ink Type: The signature appears to have been applied using a thick-tipped paint marker (likely metallic or oil-based red ink). It sits on the surface without noticeable bleeding or soak-in, consistent with glossy photo stock.
• Surface Texture: High-gloss photo paper or laminated poster medium, which shows minimal ink absorption. The signature reflects ambient light, reinforcing the likelihood of surface-bound marker ink.
• Interaction with Substrate:
• Evidence of minor ink pooling in tighter curves, which supports a live application.
• No signs of ink diffusion typical of inkjet printing, and no powder buildup or sheen consistent with laser toner.
• Smudging or Drag: No displacement or smearing visible; edges are crisp though slightly soft in curvature transitions, typical of paint-marker flow variance.

Individual Signature Analysis

• Line Quality and Flow:

• Natural variation in stroke curvature and cohesion suggest live handwriting.

• The entry and exit points (notably the initial “C”-like curve and the terminal stroke at the “y”/”t”-like tall loop) show signs of natural tapering.

• No mechanical jitter or perfect symmetry indicative of autopen usage.

• Pressure & Velocity Indicators:

• A consistent but realistic pressure application is visible in the mid-loops—slightly thicker lines in the arcs followed by taper-outs, showing pressure release.

• No artificial stroke splicing or reproduce artifacts seen in machine prints.

• Letter Form Identification:

• The initial grapheme resembles a stylized “C” followed by a rounded letter potentially representing either “U” or “a” depending on style interpretation.

• Late-stroke vertical resembles elongated “l” or “t”, aligning with known Utley traits in stylized signatures.

Collective Signature Analysis

• Internal Consistency:
  There is uniform ink application with plausible variation indicating multiple stroke speeds and momentary hesitation (e.g., looping transitions).
• Lack of Duplication:
  Pixel-level cross-comparison against available exemplars shows no signs of perfect overlay or template-based repetition. While this signature has similarities with verified Utley pieces, they do not match exactly, which reduces the likelihood of autopen use.

Red Flags

• Lack of Provenance:
  No documentation regarding where, when, or under what context this autograph was obtained. This is a significant factor limiting confidence.
• Minor Uniformities:
  There is a slightly unnatural flow at the bottom loop, though not mechanically precise—it may simply reflect hurried signing or paint-pen resistance on the glossy surface.

Final Notation: While this signature exhibits properties aligning with live signatures and no major evidence points to autopen or print reproduction, the lack of clear provenance and the potential for marker behavioral artifacts introduce minor uncertainty. Visual analysis suggests a likely authentic marker signature from Chase Utley, though not definitively conclusive without supporting documentation.
