How Authenticating Rare Coins Like the $10K 1933-S Half Can Launch Your Tech Expert Witness Career
October 1, 2025How a $10K Coin Auction Exposes Hidden Red Flags in M&A Tech Due Diligence
October 1, 2025As a CTO, I see the world through a unique lens. Technology isn’t just a tool—it’s the foundation of business resilience. When I heard about a rare coin selling for $10,000 in a Czech auction, my engineering instincts kicked in. The technical flaws? They tell a story we’ve all seen before: the high cost of cutting corners on due diligence.
The Incident: A High-Tech Red Flag in a $10K Coin Auction
That 1933-S half-dollar coin looked perfect. Too perfect. Rare coin collectors noticed the impossibly sharp details, the inconsistent lettering. The arms looked… off. Just like when a vendor promises “zero-downtime” or an API “guarantees” 99.99% uptime without a single SLA to back it up.
This isn’t about counterfeit currency. It’s about how we assess technical risk. In my career, I’ve seen the same pattern play out:
- A “perfect” solution that collapses under real-world stress
- A vendor’s glossy demo hiding brittle code
- That “free” tool that introduces more problems than it solves
Why This Matters to CTOs: It’s Not Just About Authenticity
Sure, a coin auction feels distant from our daily work. But the principles? They’re identical. Every CTO faces the same challenges when evaluating:
- Third-party APIs that promise the moon
- Open-source libraries with no maintenance history
- Internal systems that “work fine” until they don’t
- New engineers who swear their code is “production-ready”
Those suspicious coin details? In tech, they’re the poorly documented edge cases, the rate limits buried in footnotes, the vendor’s refusal to share security audit results. The $10K loss? That’s what happens when we skip the technical homework.
Strategic Planning: Building a Culture of Rigorous Due Diligence
My roadmap planning starts with one question: “What could go wrong?” Here’s how I build teams and systems that answer it:
1. Requiring Side-by-Side Comparisons
The coin experts compared genuine vs. suspect. We do the same:
- Benchmarking tools against real-world workloads (not just vendor claims)
- A/B testing libraries before production adoption
- Validating performance with actual user data, not theoretical specs
When evaluating a new AI model last year, we ran it against a subset of production data. The results? Not the 99% accuracy claimed, but 72%. That saved us from a costly mistake. if (realWorldResults > threshold) { proceed; } works better than blind trust.
2. Prioritizing High-Resolution Data
Grainy auction photos hid the coin’s flaws. In tech, low-resolution data does the same:
- Distributed tracing instead of vague “system slow” alerts
- Endpoint-level metrics not just aggregate averages
- Complete API documentation with real error examples
3. Establishing a “Trust but Verify” Process
We ask vendors: “Prove it.” Then we test:
- Load testing with realistic traffic patterns
- Dependency scanning for vulnerable third-party code
- Contractual SLAs with clear penalties
Budget Allocation: The Cost of “Too Good to Be True”
That coin’s perfect feathers were a warning sign. In tech, we face the same temptation: “This will save us 50%! This needs no maintenance! This guarantees instant results!” My budgeting reflects reality:
1. Due Diligence as a Line Item
We budget for:
- External security audits (not just vendor self-reports)
- 3-month PoCs before major purchases
- Team training in threat modeling and code review
For a recent cloud migration, we allocated $20K for PoC, $30K for migration, $50K for scaling. The PoC revealed network latency issues—avoiding a costly mistake.
2. Risk-Weighted ROI Calculations
Our ROI formulas include:
- Reputation damage from potential breaches
- Vendor stability (will they exist in 2 years?)
- Long-term costs of technical debt
3. Contingency Reserves
We keep 15% of our tech budget ready for:
- Unexpected security incidents
- Vendor contract changes
- Legacy system replacements
Managing Engineering Teams: Building a “Red Flag” Mindset
The coin debate was powered by experts who spotted inconsistencies. We cultivate the same mindset:
1. Train Engineers to Spot Inconsistencies
Our engineers learn to:
- Question sudden improvements (“Why is this suddenly 10x faster?”)
- Compare code against industry standards
- Use tools like
gitleaksto find secrets in code
gitleaks detect -s . -v has saved us from multiple credential leaks.
2. Reward Skepticism
Our culture celebrates:
- Healthy challenges (“I see a security risk here”)
- Alternative proposals (“What if we tried X?”)
- Early bug reports (“I found an edge case”)
3. Build Cross-Functional “Red Teams”
We form review groups to:
- Attack our own systems before others do
- Audit third-party tools beyond marketing claims
- Assess technical debt honestly
Tech Roadmaps: Designing for Resilience
The coin’s flaws were subtle but critical. Our systems need the same attention to detail:
1. Embed Verification at Every Layer
We build with:
- Input validation (never trust user data)
- Output verification (check even “trusted” sources)
- Audit trails (who changed what, when)
2. Prioritize Observability
Our systems provide:
- Real-time dashboards showing actual performance
- Structured logs for fast debugging
- Distributed tracing to track requests end-to-end
3. Build in “Failsafes”
Every critical system has:
- Rate limiting to prevent abuse
- Rollback mechanisms for quick recovery
- Automated backup verification
Conclusion: The CTO’s Duty — Beyond the Obvious
That $10K auction wasn’t about a bad coin. It was about the cost of assuming instead of verifying. My job isn’t just to build technology. It’s to build systems that survive when things go wrong.
• Make due diligence routine—from code commits to vendor contracts
• Budget for scrutiny as much as for innovation
• Train teams to question as much as to execute
• Design systems to self-check at every step
In tech, there are no “too good to be true” solutions. Just solutions that need more scrutiny. The next “perfect” opportunity could be the one that breaks your system. Find the flaws early—before they cost you far more than $10K.
