November 11, 2025From Camera to Cash Flow: How I Built a $50K Coin Photography Course
Want to know the coolest part about teaching online? That moment when your hobby starts covering mortgage payments. Believe me – I never thought photographing coins would let me quit my accounting job. But here we are! Let me show you exactly how I transformed my numismatic passion into a thriving Udemy course that earned $50K last year.
The Side Hobby That Accidentally Went Viral
It all began with me snapping coin pics for Reddit. Slowly, something unexpected happened:
- My DMs flooded with “How’d you get that luster?”
- Forum members begged for lighting diagrams
- Seasoned collectors asked about my $40 DIY lightbox
That’s when I realized – my “just for fun” photos had uncovered a hungry audience.
Step 1: Proving People Would Pay (Before Filming)
No Guesswork, Just Cold Hard Data
I avoided wasting months by validating demand first:
- Forum snooping: Bookmarked every “help with coin photos” post
- 3-question polls: Asked collectors their biggest frustrations
- Secret shopper: Took competing courses to spot missing pieces
Turns out, everyone hated the tech jargon in existing tutorials. My “regular person” approach became my golden ticket.
Step 2: Crafting the Actual Course
What My Students Actually Needed
Forget theory – my collectors wanted actionable steps:
- Gear breakdowns (my favorite $8 macro lens hack)
- Lighting setups for proof coins vs circulated pieces
- Simple Lightroom tweaks that make details pop
- Pro results using smartphone cameras
My Bite-Sized Creation Formula
Each module follows this rhythm:
- Quick intro (under 5 mins – attention spans are short!)
- Printable cheat sheet with camera settings
- Real coin demo from 3 angles
- “Your Turn” challenge with before/after examples
- Office hours-style Q&A
Step 3: Platform Showdown – Where to Host
Udemy vs Teachable: Real Numbers
After 18 months on both, here’s my honest take:
| Teachable | Udemy | |
|---|---|---|
| Price Freedom | Set your own ($97 works best) | Forced discounts ($19 sales) |
| Finding Students | All on you | Built-in traffic |
| Your Cut | Keep 97% | Keep 37% (ouch) |
My winning combo? Use Udemy as a “free sample” funnel to my premium Teachable course.
Step 4: Marketing That Doesn’t Feel Sleazy
Organic Growth Tactics That Worked
1. Value-first YouTube: “Coin Lighting Hacks” videos with course links
2. Forum karma farming: Solving photo problems WITHOUT pitching
3. Grading service collabs: NGC loved my “Submission-Ready Photos” guide
Launch Timeline That Made $12k Fast
My 30-day secret sauce:
- Week 1: “Sneak peek” shots in collector groups
- Week 2: $49 early-bird offer (50 slots only)
- Week 3: Retargeting ads showing student wins
- Week 4: Live AMA addressing launch doubts
Why This Beats Trading Hours for Dollars
Three years later, my course runs like a vending machine:
- 5 hours monthly upkeep (mostly fun student chats)
- Paid for my Portugal coin-hunting trip
- Let me ditch spreadsheets forever
If a guy who used to photograph Lincoln cents under desk lamps can do this? You’ve got skills worth sharing. Start small, listen to your people, and remember – every expert was once the clueless newbie asking for help.
