How Mastering Coin Grading Slab Expertise Can Elevate Your Consulting Rates to $200/hr+
September 23, 2025How to Write and Publish a Technical Book: A Guide from an O’Reilly Author
September 23, 2025Sharing what you know can be one of the most rewarding ways to earn money. Let me show you how I turned my love for coin slabs—like the NGC Fattie 3.0 with its gold embossed reverse, or the PCGS 2.2 with green certification—into a $50,000 online course. It’s easier than you might think!
Why Online Courses Are Your Ticket to Passive Income
Digital products like online courses scale beautifully. Once you create one, it sells again and again. My course on coin slab aesthetics and grading found a hungry audience. Platforms like Teachable and Udemy made delivery simple.
Finding Your Profitable Niche
Your unique knowledge has value. For me, it was the small details—like why collectors love NGC slabs with lime-green ink or PCGS Regency holders. I noticed people were searching for this info but couldn’t find it all in one place. Start by checking forums and social media. See where people are asking questions you can answer.
Creating Your Online Course Content
Great content is key. I broke my course into clear modules: slab types, aesthetics, grading, and even storage tips (like how small ANACS slabs save space). Each section had videos, downloads, and quizzes to keep things interesting.
Using Visuals and Real Examples
Show, don’t just tell. I used sharp photos—comparing an NGC Fattie 3.0 to a PCGS 2.2, for example. I even added interactive sliders so students could explore differences themselves. It made the lessons stick.
Choosing the Right Platform: Teachable vs. Udemy
I use Teachable for control and better profits. But I also list on Udemy to reach their built-in audience. Teachable lets you brand everything your way. Udemy markets for you but takes a cut. Think about what matters more to you: ownership or reach.
Quick Technical Tips
Embed videos smoothly with an <iframe>. Optimize your sales page with phrases like “coin slab course” or “grading consistency.” Here’s a simple code snippet for adding a promo video:

Marketing Your Online Course for Maximum Sales
Talk about what you know. I wrote blog posts and hosted webinars on topics like why gold embossed reverses are so popular. It built trust and sent traffic straight to my course.
Using Ads and Partnerships
Try targeted ads on Facebook or Google. Use keywords like “best coin slabs” or “passive income from collecting.” Team up with influencers in your niche—their reviews can boost your credibility and sales.
Scaling and Automating for Passive Income
After launch, automate as much as you can. Set up email sequences for new students and follow-ups. I use Zapier to send congratulatory notes when someone finishes a module. It keeps things personal without extra work.
Tracking Performance and Making Improvements
Watch your metrics. Completion rates and refund requests tell you a lot. I added a section on SEGS and CACG slabs after students asked—it made the course even better.
Your Path to Course Success
Turn what you know into income. Find your niche, create engaging content, pick a platform, and share it widely. I did it with coin slabs, and you can do it too. Start today—sketch out your first module and take that first step!
