From Coin Nerd to Course Creator: My $75k Journey
Who knew my obsession with spotting fake 19th-century coins could pay the mortgage? Let me show you exactly how I turned my numismatic passion into a profitable online course that’s earned over $75,000 while I sleep.
Finding Your Goldmine Knowledge
Three recurring nightmares kept popping up in collector forums:
- Fakes everywhere: “Even common date cents get counterfeited now”
- Learning overload: “You need a PhD in vintage coins to avoid scams”
- Marketplace anxiety: “I break out in cold sweats buying on eBay”
Proving People Would Pay
Through forum lurking, I confirmed collectors needed:
- Visual cheat sheets (like that infamous fake 1875-CC half dollar)
- Trusted resource directories (PCGS tools, CoinWeek deep cuts)
- Safe buying playbooks (why Heritage Auctions beats random sellers)
Building Your Money-Making Course
My 8-Step Authentication Blueprint
The exact structure that converted browsers into buyers:
- Module 1: Understanding the Fake Coin Underground (1794-1891)
- Module 2: Coin Autopsy 101 – Weight, Sound & Surface Tells
- Module 3: Side-by-Side Fake Spotting (using real forum examples)
- Module 4: eBay Minefield Navigation
- Module 5: Cracking Grading Service Codes (PCGS/NGC labels)
- Module 6: Collecting Counterfeits Legally
- Module 7: Building Your Anti-Fraud Library
- Module 8: Crowdsourcing Authenticity Checks
What Made My Content Stick
I still remember the lightbulb moment when I created this interactive slider comparing real vs. fake coins:
“ Classic eBay fake – notice the mushy details?”
Screen recordings of live PCGS verifications became student favorites – there’s nothing like watching me sweat through an authentication!
Platform Wars: Where To Host
Teachable vs. Udemy – The Real Deal
| What Matters | Teachable | Udemy |
|---|---|---|
| Setting Prices | You’re the boss | Marketplace decides |
| Student Access | Direct connection | They’re Udemy’s students |
| Fees | Small slice | Half your pie |
I funnel students to Teachable but keep a mini-course on Udemy as a “gateway drug.”
