November 20, 2025How I Turned Coin Grading Into a $50K Online Course Business
Remember that dusty coin collection in my attic? It unexpectedly became my golden ticket to five figures in passive income. Here’s exactly how I transformed my numismatic passion into a thriving online course business – and how you can do the same with your expertise.
The Unexpected Profit in What You Know
Spotting Your Money-Making Knowledge
Three lightbulb moments revealed my coin grading skills were worth serious money:
- Clear skill gaps: I noticed fresh collectors constantly mixed up strike quality and wear patterns
- Frustration points: Even veterans struggled spotting the difference between MS65 and MS66 grades
- Proven spending: Watching collectors drop $300+ on reference books showed real market potential
Testing Real Demand (No Guessing)
Here’s a real example from my research:
// Simple demand check I actually used
const monthlySearches = 4500; // "coin grading" searches
const avgCoursePrice = 197;
const conversionRate = 0.03; // Conservative 3% sign-up rate
const potentialRevenue = (monthlySearches * conversionRate * avgCoursePrice).toFixed(0);
console.log(`$ ${potentialRevenue}/month potential`); // Shows "$26,595/month"
Seeing those numbers convinced me to take the leap.
Crafting Your Course Like a Pro (On a Budget)
My Barebones Production Setup
Creating 47 modules cost less than you’d think:
- Camera: Logitech C922 Pro ($99) – perfect for coin close-ups at my kitchen table studio
- Editing: Free tools like OBS Studio and DaVinci Resolve kept costs at zero
- Graphics: Canva Pro ($12.99/month) for side-by-side coin comparison charts
“Students’ grading accuracy jumped 63% when I showed real examples of AU58 vs MS65 coins – proof that visuals beat theory every time.”
Choosing Your Course Home Base
My platform showdown revealed key differences:
| Teachable | Udemy | |
|---|---|---|
| Pricing Freedom | Set your own rates | Sales controlled by platform |
| Student Access | Full customer list | Limited contact info |
| Fees | 5% + $1 per sale | 50% cut on most sales |
Teachable became my home base while I used Udemy as a ‘free sample’ generator.
