How I Built a $50,000 Online Course Selling Coin Grading and Auction Expertise
September 30, 2025How Deep Knowledge of Coin Auctions Can Lead to a Career as a Tech Expert Witness in Legal Tech
September 30, 2025Want to know a secret? Writing a technical book isn’t about fancy jargon or trying to sound like a textbook. It’s about solving real problems for real people. When I started writing about problem coins in third-party graded (TPG) holders, I wasn’t chasing fame or fortune. I was filling a gap I’d seen firsthand – collectors getting burned, auction houses scratching their heads, and grading services pointing fingers.
My journey from scattered notes to published author taught me this: the best technical books don’t just share knowledge – they create it. Let me walk you through exactly how I did it, so you can too.
Why Write a Technical Book on a Niche Topic?
Look, if you’re thinking about writing “another blockchain book,” save yourself the trouble. I chose problem coins in TPG holders because it was specific, it was contentious, and most importantly – nobody had really nailed it. Here’s what I discovered about niche topics:
- You become the expert by default: When your book is the only one addressing “PCGS vs CAC liability for altered coins,” you own that conversation.
- The right readers find you: Serious collectors and auction professionals aren’t looking for fluff – they need answers to their specific problems.
- Publishers notice specialists: My focused approach got me more attention from O’Reilly and Apress than any general “coin collecting” book ever would.
Here’s what happened: A few months after my book came out, I got an email from a coin dealer in California. He’d used my chapter on liability during an auction dispute and won the case. That’s the power of a well-targeted technical book.
The 3 Criteria for Choosing a Niche Topic
Before you write a single word, ask these questions:
- Is there a real problem? In my case, collectors were losing money on misgraded coins, but the legal framework was unclear. That tension created the need for my book.
- Do you have unique access? I spent months building relationships with graders and auctioneers. Their insights became the backbone of multiple chapters.
- Will this matter long-term? Unlike trendy tech, grading controversies aren’t going away. Coins will always get altered, and graders will always debate.
Structuring Your Book: From Chaos to Clarity
My first outline was a mess – all over the place, like my thinking. What fixed it? Looking at my book like I would a well-organized codebase: modular, focused, and solving specific problems in order.
My book, “Graded But Not Perfect: The Hidden Liabilities of TPG-Certified Coins,” follows this flow:
- Chapter 1: The Illusion of Perfection (Breaking down why those shiny plastic slabs aren’t foolproof)
- Chapter 2: Defining a “Problem” Coin (What makes a coin “problematic,” from light cleaning to major alterations)
- Chapter 3: Case Studies (The real stories behind the headlines – and the lessons they teach)
- Chapter 4: Legal and Market Liabilities (Who’s actually responsible when things go wrong?)
- Chapter 5: The Collector’s Playbook (How to protect yourself, from pre-bid research to post-sale disputes)
Actionable Tip: Use Code-Like Structure
I had an ah-ha moment when I realized: my book could follow the same logic as a function. Here’s how it works:
function handleProblemCoin(coin, auctionHouse, tpg) {
if (isAltered(coin)) {
return auctionHouse.buybackPolicy();
} else if (isCleaned(coin)) {
return tpg.reviewProcess();
} else {
return "buyerBeware";
}
}Each chapter became a “function” solving a specific problem. Technical readers loved this approach – it made the information stick.
Pitching Publishers: What O’Reilly, Manning, and Apress Want
Here’s what most don’t get: publishers aren’t looking for passion. They’re looking for sales. My pitch succeeded because I spoke their language:
1. The “Hook”
I opened with a real story, not a sales pitch:
“Last year, a collector paid $120,000 for a CAC-approved coin. Two weeks later, he discovered chemical alteration. The auction house wouldn’t budge. This book explains why situations like this happen – and how to prevent them.”
2. The Audience
Specificity wins. I didn’t say “coin collectors.” I said:
- Who’s buying? (Active bidders at Heritage Auctions, members of PCGS Premium Members, professional coin dealers)
- Where they congregate: (The PCGS message boards, r/coins Reddit posts, NGC chat threads)
- What keeps them up at night: (Overpaying, legal risks, emotional disappointment)
3. Your Credibility
Publishers check your background. I highlighted:
- My CoinWeek article on CAC’s liability framework
- ANA seminar presentations I’d given
- My network (I had contacts at all major grading services)
4. Competitive Analysis
I showed I understood the market. My book wasn’t just “another coin book” – it was the missing piece:
- “The Official Guide to Coin Grading” (Too basic for serious collectors)
- “Coin Collecting for Dummies” (Not technical enough for professionals)
Writing Process: From First Draft to Final Edits
Writing a book is brutal. Here’s what kept me going:
1. The 20% Rule
I spent 20% of my time outlining, 80% writing. My Chapter 3 outline looked like this:
3.1 Case Study: The 1916-D Mercury Dime
- The problem: Hidden hairline scratches
- The auction: Heritage, 2022
- What happened: Buyer's buyback request denied
- The key takeaway: How "as is" clauses work in practice
3.2 Case Study: The 1804 Silver Dollar
- The problem: Suspicious toning
- The auction: Stack's Bowers, 2021
- What happened: CAC removed their sticker
- The key takeaway: What CAC's sticker actually means
2. Collaborate with Experts
My best sources were the graders themselves. Their quotes became gold:
“Our job is to grade what’s on the label, not guarantee what’s inside the holder.” —PCGS Grader (2023)
3. Use Visuals
Publishers eat up well-designed diagrams. In my book:
- Flowcharts showing the PCGS problem coin process
- Comparison tables laying out PCGS vs NGC vs CAC policies side-by-side
Building Your Audience: Before, During, and After Publication
Here’s the truth: your book won’t market itself. I started building buzz 6 months before launch:
1. Pre-Launch
- Guest posts on CoinWeek established my expertise
- Webinars about CAC review processes built my email list
- ConvertKit helped me grow a pre-launch list of 500+ serious collectors
2. Launch
- Publisher support got my book in front of O’Reilly’s massive audience
- Industry blurbs from experts like David Hall added credibility
- Content repurposing turned chapters into LinkedIn posts and YouTube shorts
3. Post-Launch
- SEO targeting phrases like “PCGS problem coins” and “auction buyback policies”
- Community engagement – I answered questions on PCGS forums and linked to relevant sections
Key Takeaways for Aspiring Authors
- Niche down hard: My book succeeds because it’s about liability, not just coins.
- Let data tell your story: Case studies and expert interviews prove you know your stuff.
- Start marketing early: Your book is just the first chapter in building your brand.
- Structure is everything: Break problems down like you’re coding a solution.
Conclusion
My book didn’t just sit on shelves – it changed conversations in the coin world. Collectors now approach auctions differently. Auction houses cite my work in their terms. Grading services have updated their policies.
That’s the power of a technical book done right. Not for the money. Not for the fame. But for the impact.
I’m not special. You don’t need to be either. What you need is a specific problem to solve, data to back your solutions, and the persistence to see it through.
The next great technical book isn’t waiting for the perfect moment. It’s waiting for someone like you to write it. So grab your notes, start outlining, and get to work. The collectors, developers, or professionals in your niche need what you have to say.
Your first chapter starts today.
