A CTO’s Strategic Playbook: Lessons in Decision-Making, Validation, and Resource Allocation from a 1946 Jefferson Nickel

As a CTO, I spend my days balancing innovation with practicality. How do I decide what tech bets are worth making? What gets the green light—and what gets shelved? The answer came to me in an unexpected place: an old coin forum discussing the humble 1946 Jefferson nickel.

The Parallel Between Rare Coin Authentication and Technical Decision-Making

I stumbled on a thread about a potential “transitional mint error” in a 1946 nickel. The excitement was palpable. But as engineers and coin experts weighed in, I saw a mirror of my own world: the trap of chasing outliers without proof.

That “once-in-a-lifetime” discovery? It rarely is. In my 15 years leading engineering teams, I’ve seen this play out again and again:

• A junior dev spots a “revolutionary” pattern in logs—but it’s just noise.
• An exec loves a new tool because it “worked for Amazon”—without testing it in our stack.
• A team spends months building a feature for one power user, ignoring 99% of customers.

Just like that nickel, not every anomaly is gold. And not every shiny idea deserves your budget.

Why Edge Cases Are Costly (and How to Avoid the Trap)

The coin owner thought they’d found a rare wartime nickel. Their evidence? It wasn’t magnetic. But here’s the catch: both regular and wartime nickels are non-magnetic. One test, one data point—no validation.

Sound familiar? We’ve all been there. In tech, this looks like:

• Adopting a new framework because “everyone’s talking about it”—without testing scalability.
• Optimizing a service for a 0.1% edge case, while most users wait longer.
• Building a feature based on one “squeaky wheel” user’s feedback.

Pro tip: Real validation means multiple proofs. For coins: weight, composition scans, historical records. For software: benchmarks, user data, security checks. Always ask: What else could explain this?

Strategic Planning: When to Invest in Validation (and When to Walk Away)

The owner debated paying $100+ for PCGS authentication. Sound like your board meeting debates over expensive tools? The real question isn’t “Can we?”—it’s “Should we?”

Here’s what this looks like in my world:

• Do we pay for enterprise-grade observability, or build lightweight in-house?
• Is a third-party security audit worth it, or can we self-validate?
• Should we fork over $50k for that AI platform, or train our own models?

The Validation Cost Matrix for CTOs

My rule: Only validate when the upside justifies the cost. I use this:


if (potential_impact * probability_of_success > validation_cost * risk_multiplier) {
// Go ahead
budget_approved();
prepare_for_failure();
} else {
// Hit pause
document_risk();
focus_on_core();
}


That nickel? Low odds, high cost, zero upside. Same as that “critical” bug affecting 1 in 10,000 users. Sometimes, the best move is to move on.

Building a Culture of Evidence-Based Leadership

Here’s a sobering one: The coin owner got bad info from an AI. AI hallucinations are the new “gut feeling”—and just as dangerous.

In my teams, we’ve built a “prove it” culture:

• AI code? Reviewed + tested.
• Vendor promises? Piloted + benchmarked.
• Estimates? Backed by data, not guesses.

Actionable Framework: The 3-Layer Validation Check

Here’s my go-to for cutting through the noise:

1. Falsifiability first: “What would prove this wrong?” (If this nickel has silver, an XRF scan should show it.)
2. Cheap test: “Can we validate this without big spend?” (Free XRF tool vs. PCGS?)
3. Big picture: “Does this fit our goals?” (Is this part of our strategy, or a distraction?)

Translation for tech: Can we disprove it? Can we test it fast? Does it move the needle?

Managing Engineering Teams: From “Eureka” to “Evidence”

Every team has that one engineer chasing a “white whale”—some rare bug, perfect solution. My fix? The “10x Rule”:

• Impact: “If this is real, does it 10x our metrics?”
• Probability: “How sure are we?”
• Cost: “What else are we not doing for this?”

Case in point: When a team claimed they’d found a “10x faster database,” I asked: “Tested against our queries? Migration cost? What’s the failure mode?”

Hiring for Validation Skills

Today, I screen for what I call “skepticism IQ”:

• Candidates who ask, “Why are we building this?” in interviews.
• Engineers who document edge cases before writing code.
• Leaders who default to data, not hunches.

Just like those coin experts: They didn’t trust the magnet. They demanded proof.

Budget Allocation: The “Nickel Principle”

Here’s my core philosophy: Not every rare thing is valuable. Not every “innovative” idea is smart.

“That 1946 nickel? Worth 5 cents until proven otherwise. Same goes for your tech projects.”

My budget rule:

• 70%: Core work we know moves the needle.
• 20%: Quick tests of promising ideas.
• 10%: “Nickel bets”—high-risk, high-reward—but only after the 3-layer check.

Conclusion: The CTO’s Mantra

That old nickel? Just a nickel. But the lesson? Gold.

As tech leaders, our job isn’t to chase every shiny thing. It’s to:

• Validate before investing (like skipping PCGS until we had real proof).
• Focus on what matters (core users, not outliers).
• Build teams that question (because “I read it on the internet” isn’t a strategy).
• Apply the “Nickel Principle” daily: “Is this truly valuable, or just rare?”

In tech and in coins, the real win isn’t finding the outlier. It’s knowing when to walk away.
