September 24, 2025From Coin Collector to Edupreneur: My Journey Creating Digital Courses
Sharing what you know can be one of the most rewarding ways to earn income. Let me show you how I turned my passion for rare coin grading into a $74,000 online course empire. It all started with forum chats about coins like the 1838 Seated Dime. Now, I teach collectors across the globe.
Spotting the Knowledge Gap
After countless debates—like those P01 vs FR02 disagreements—I saw a real need for clear, standardized education. My course outline grew from these very conversations with fellow enthusiasts:
- Understanding grading scale differences (PCGS vs NGC vs CAC)
- How to evaluate surfaces on worn coins
- Strategies for analyzing market value
- Streamlining your submission process
Course Creation: From Idea to Reality
Building Your Content
I used the 80/20 rule: focus on the 20% of knowledge that gives 80% of results. Every module includes:
- Tutorials on high-resolution coin photography
- Videos comparing grades side by side
- Interactive simulations for practice grading
- Quick-reference PDF guides
“Make it actionable. Students should use each lesson right away with their own collections.”
My Affordable Tech Setup
You don’t need to break the bank. My whole production cost under $2,000:
- Sony ZV-1 camera ($798)
- Rode Wireless Go II mic ($299)
- Teachable platform ($99/month)
- Canva Pro for graphics ($12.99/month)
Launch Strategy That Made $23k in 30 Days
Growing My Email List Before Launch
I built an email list of 1,200 keen collectors by offering:
- A free “Grade Estimation Calculator” tool
- A PDF guide: “5 Common Grading Mistakes”
- Strategic forum signature campaigns
