How I Turned My Passion for Rare Coin Collecting into a $50,000 Online Course
September 25, 2025How Mastering Your Tech ‘Watchlist’ Can Launch Your Career as a High-Demand Expert Witness
September 25, 2025Want to establish yourself as an expert? Writing a technical book is one of the best ways to do it. I’m a published O’Reilly author, and in this post, I’ll walk you through my entire process—from shaping your idea to pitching publishers and finally holding your book in your hands.
Why Coin Collecting Deserves a Technical Book
Niche topics like coin collecting are perfect for technical books. Why? Because collectors aren’t just hobbyists—they’re investigators, historians, and data analysts rolled into one.
Think about forum discussions tracking rare coins like the 1933 Double Eagle. There’s a real hunger for structured, technical knowledge here. A great book bridges the gap between casual interest and true expertise.
Finding Your Technical Angle
When I wrote my first book, I focused on systems and data. For coin collecting, that could mean authentication algorithms, market analysis, or preservation science.
Your goal? Turn those forum watchlists into a practical, technical guide.
Crafting a Winning Book Proposal
Publishers like O’Reilly, Manning, and Apress want proposals that show clear demand and technical depth. Here’s how to build yours.
Market Analysis: Who Needs This Book?
Your readers are collectors, dealers, and historians. Look at existing books—what’s missing? Maybe no one’s combined numismatic history with modern data analysis. That’s your opening.
Outline with Technical Rigor
Structure your book into clear sections. Start with fundamentals like grading systems. Move to advanced topics like counterfeit detection. End with practical projects, like building a digital watchlist.
Don’t shy away from code. Here’s a simple Python example for scraping auction data:
# Example Python snippet for tracking auction prices
import requests
from bs4 import BeautifulSoup
def scrape_auction_data(url):
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
# Extract coin details and prices
return data
Building an Audience Before You Write
Start engaging early. Join forum conversations. Share insights. Answer questions. Tease your book’s concepts. This builds a community that’s ready to read your work.
Use Social Proof
As an O’Reilly author, I’ve found that sharing early content really helps. For a coin book, try publishing articles on rare coin analytics or preservation. Platforms like GitHub or Medium are great for this.
Navigating the Writing Process
Technical writing needs precision. Use specific examples—like the 1787 Fugio Cent or the 1856-S half dollar. Every chapter should solve a real problem, such as authenticating a coin or building a better collection strategy.
Actionable Takeaways for Each Chapter
- Grading Chapter: Add step-by-step guides with comparison images.
- Market Trends: Include templates for price tracking.
- Digital Tools: Share code for custom watchlists.
Pitching to Publishers: O’Reilly, Manning, and Beyond
Your pitch should highlight what makes your book unique. For coin collecting, focus on the mix of history, data, and hands-on collecting. Publishers love books that cross disciplines.
Sample Pitch Paragraph
“This book brings together numismatic passion and technical skill. Readers will learn to build automated watchlists, analyze market trends, and care for their collections using modern tools. It’s written for collectors ready to take their expertise to the next level.”
Your Path to Becoming a Published Author
Writing a technical book turns what you know into something lasting. By focusing on real problems—like those you see in forums—you create real value for readers.
Start with a strong proposal. Connect with your audience early. And make every chapter useful. You’ve got this.
