How I Wrote a Technical Book on Coin Grading: From Concept to Publication with O’Reilly
October 1, 2025A CTO’s Lens on the 1880/79-O VAM-4 Coin: Strategic Decision-Making in Technology and Grading Uncertainty
October 1, 2025When software is at the center of a legal dispute, lawyers need someone who can cut through the noise. That’s where tech expert witnesses come in. I’ve spent over a decade analyzing digital evidence, source code, and technical claims in high-stakes litigation. Let me share a secret: it’s not just about knowing code—it’s about knowing how to prove it in court. The same skills used to evaluate a rare 1880/79-O VAM-4 Morgan dollar—forensic rigor, attention to detail, and interpretive skill—transfer directly to source code review for legal cases, intellectual property disputes, and litigation consulting.
Why Technical Expertise = Legal Leverage
In legal tech careers, the courtroom doesn’t care about your GitHub stars or startup equity. It cares about three things: credibility, reproducibility, and defensibility. Just like a coin’s surface can be altered, cleaned, or misgraded, software can be tampered with, misrepresented, or poorly documented. When millions are on the line—in patent infringement, data breaches, or open-source licensing disputes—the expert who can detect anomalies, trace changes, and explain technical truth to a jury becomes indispensable.
The Forensic Mindset: From Coins to Code
Consider coin grading. Is the surface altered? Has the luster been compromised? Was the grade inflated? These questions mirror my approach to reviewing source code for legal disputes. For example:
- Was the code modified after the fact to conceal malfeasance?
- Does the commit history match the claimed development timeline?
- Are there signs of code obfuscation, backdated comments, or artificial versions to mislead auditors?
Just as a coin grader scrutinizes haze, luster breaks, and wispy lines to detect friction or cleaning, I analyze git history, metadata timestamps, and code structure to detect anomalies. The tools differ, but the mindset is the same: look for what’s not supposed to be there, and question what’s missing.
Case Example: Detecting Code Surface Alteration
In one IP dispute, the opposing party claimed their software was developed in 2018. But a forensic review of the git log revealed red flags:
- Commit timestamps altered using
git commit --amend --date="2018-05-01" - Files with modern API calls (e.g.,
fetchwithasync/await) in 2018 commits (syntax not widely adopted until 2020) - Missing intermediate commits expected in a 2-year development cycle
Using source code review for legal cases, I showed the repository had been backdated and reconstructed—like a coin altered to appear older. In court, we presented a timeline graph showing the anomalies in timestamp consistency and syntax anachronisms. The jury got it—because we spoke their language.
Litigation Consulting: When Tech Meets Testimony
Being a tech expert witness isn’t just about analysis—it’s about translation. Lawyers and judges don’t need to know Git. They need to know what it means when a commit is backdated or a file is missing from version control.
Your Role: The Bridge Between Code and Courtroom
As a consultant, your job is to:
- Identify technical anomalies (suspicious code patterns, inconsistent docs, missing logs)
- Document findings defensibly (chain of custody, audit trails, reproducible steps)
- Explain complexity simply (e.g., “This is like finding a modern car part in a 1920s vehicle”)
- Withstand cross-examination under oath, with evidence-backed reasoning
One mistake? Overloading the jury with jargon. Use analogies instead. In a patent dispute over image recognition algorithms, I compared the contested feature to “a coin’s luster—shiny on the surface, but if it’s been polished with chemicals, the underlying metal is damaged.” The analogy made the flaw intuitive: just as a cleaned coin loses authenticity, over-optimized code may sacrifice integrity for performance.
Source Code Review: The Technical Foundation of Your Testimony
Let’s talk mechanics. Source code review for legal cases isn’t about line-by-line bug hunting—it’s about provenance, authenticity, and intent.
3 Critical Steps in Forensic Code Review
1. Metadata & Version Control Analysis
Use tools like git log --stat, gitk, or GitLab’s audit logs to verify:
- Who committed what, when, and from where (IP logs, device IDs)
- Whether commits were rebased or reordered post-dispute
- Presence of orphaned branches or force-pushed history
2. Code Paleontology
Look for anachronisms:
- Does a 2015 file use
async/await(ES2017)? - Is there a
package.jsonwithreact@18.2.0in a 2010 repo?
3. Dependency & License Forensics
In IP disputes, check package-lock.json, requirements.txt, or go.mod for:
- Unlicensed or GPL-licensed libraries in proprietary code
- Dependencies added after the dispute began
- Obfuscated or minified third-party code
Code Snippet: Detecting Backdated Commits
Here’s a bash script to flag suspicious commits:
#!/bin/bash
for commit in $(git rev-list --all); do
commit_date=$(git show -s --format=%ci $commit)
author_date=$(git show -s --format=%ai $commit)
if [[ "$commit_date" != "$author_date" ]]; then
echo "[SUSPICIOUS] Commit $commit has mismatched dates:"
echo " Commit: $commit_date"
echo " Author: $author_date"
fi
doneThis exposes commits where the committer retroactively changed the timestamp—a red flag in litigation.
How to Build a Career in Legal Tech Expertise
If you’re a CTO, freelancer, or VC, this isn’t just another gig—it’s a high-margin, recession-resilient path.
Step 1: Develop Deep, Niche Expertise
You don’t need to be a generalist. Pick a domain:
- Blockchain (smart contract audits)
- AI/ML (model training data provenance)
- Cybersecurity (breach forensic analysis)
- Open-source licensing (GPL compliance)
Then, document your findings. Write blog posts. Publish GitHub repos with forensic scripts. Contribute to open-source audits. Build a portfolio of defensible analysis.
Step 2: Get Certified (But Don’t Rely on It)
Certifications like CFE (Certified Forensic Examiner) or CEH (Certified Ethical Hacker) help, but credibility comes from case experience. Start with smaller cases—local IP disputes, contract breaches—and work your way up.
Step 3: Master the Art of Testimony
The courtroom is a performance. Practice:
- Writing clear, concise reports (bullet points, not walls of text)
- Using visuals (timelines, code diffs, flowcharts)
- Staying calm under cross-examination (“I don’t know, but here’s how I’d find out”)
The Future of Tech Expert Witnessing
Just as the 1880/79-O VAM-4 coin’s value hinges on surface integrity, your expert testimony hinges on forensic rigor. The demand for tech expert witnesses is growing—across patent litigation, data privacy lawsuits, and AI disputes—with compensation often hitting $300–$800/hour. By mastering source code review for legal cases, intellectual property disputes, and litigation consulting, you’re not just building a career. You’re becoming a guardian of truth in the digital age. Start today. Analyze a repo. Write a report. Build your reputation. Because in the courtroom, the expert who can prove it wins.
