How I Turned My Niche Coin Expertise Into a $50K Online Course on Teachable and Udemy
October 6, 2025How Deep Technical Expertise in Source Code Analysis Can Launch Your Career as a Tech Expert Witness
October 6, 2025Writing a technical book is a powerful way to build authority. I’m going to walk you through my entire process—from structuring content to pitching publishers and writing the book itself. It’s the same approach I used when writing my technical book on coin grading.
Why Write a Technical Book?
As an author published with O’Reilly, I’ve seen how a well-researched technical book can boost your career. Whether you’re a CTO building credibility or a freelancer attracting better clients, writing a book establishes you as an expert.
My own journey started with a niche interest—much like the detailed world of coin grading you find in collector forums—and grew into a full guide.
Structuring Your Content
Before you write anything, get your structure right. For my coin grading book, I broke it into clear sections: an intro to numismatics, grading criteria, case studies (like the 1945 D DDO Ten Centavos), and tips for collectors.
Outline with Precision
Begin with a detailed outline. Split each chapter into subsections. Build from basics to advanced topics. For example, Chapter 1 covered coin history. Chapter 5 moved into specific varieties and their market value.
Use Examples and Structured Content
Even non-technical topics benefit from clear examples. Here’s how I presented grading criteria in a simple table:
Grading Scale:
- MS-70: Perfect
- AU-50: Light wear
- ...
Crafting a Winning Book Proposal
Publishers like O’Reilly, Manning, and Apress get many proposals. Yours needs to shine. Focus on three things: market need, your unique angle, and your platform.
Show There’s Demand
Use data to prove your audience exists. For coin grading, I pointed to forum threads and collector groups. I included numbers—like 341 collectors tracking a specific variety—to show real interest.
Highlight Your Expertise
Share your credentials. If you’ve contributed to forums or have special knowledge, say so. My background with US Philippine coins helped me stand out.
Navigating the Writing Process
Writing a technical book is a marathon. Set a realistic schedule and keep to it. I spent 3 months on research, 6 months writing, and 2 months revising.
Use Tools to Stay Organized
Try version control like Git for your manuscript, or use Google Docs for collaboration. Here’s a snippet from my workflow:
git commit -m "Added chapter on DDO varieties"
Get Feedback from Experts
Share drafts with beta readers. For my book, numismatists checked technical details to make sure terms like “Allen-9.05c” were used correctly.
Building an Audience Before Publication
Start promoting your book early. Write blog posts, join social media conversations, and take part in forums—without overselling. I shared insights in coin grading groups, which built excitement.
Create Extra Content
Make cheat sheets, videos, or webinars. I put together a free grading guide that brought visitors to my book’s landing page.
Pitching to Publishers
Choose publishers that fit your topic. O’Reilly is great for tech, but Manning or Apress might suit niche subjects. Tailor your pitch. For coin grading, I emphasized its mix of history, finance, and tech.
Include a Sample Chapter
Send a polished chapter, like one on “Evaluating 1945 D DDO Varieties,” to show your writing and expertise.
Thought Leadership and Next Steps
After publication, use your book to find speaking gigs, consulting work, or premium content. My book led to workshops and stronger credibility among collectors.
Final Thoughts
Writing a technical book changes how people see you. It takes dedication, but the rewards are worth it. Build an audience, use clear examples, and focus on practical value. Start with a topic you love—like coin grading or coding—and follow these steps to become a published author.
