November 11, 2025From Coin Collector to Course Creator: How I Turned Passion into $50k+
Remember that hobby keeping you up at night? For me, it was US/Philippine coins. What started as weekend research became my golden ticket – I transformed numismatic expertise into a thriving online course business. Today, I’ll walk you through how I created a six-figure education product from scratch, using nothing but knowledge collectors desperately needed.
Spotting the Coin Valuation Void
When PCGS pulled their US-Philippine coin guide, forums exploded with frustration. As someone who’d spent years:
- Decoding Greysheet pricing patterns
- Tracking Heritage Auction results like a hawk
- Comparing Stack’s Bowers final prices
- Building Numista’s most detailed profiles
I suddenly realized – my spreadsheet obsession could solve real problems. Fragmented information was costing collectors money and time. That’s when my “aha” moment hit: organized knowledge presented the perfect online course opportunity.
Proving People Would Pay
Before recording a single lesson, I confirmed the market:
- Searches for “US Philippines coin values” jumped 200%
- Reddit threads showed collectors struggling daily
- My $27 mini-course on grading basics sold 89 copies in week one
The results shocked me – people weren’t just willing to pay, they were desperate for clear guidance.
Crafting the Ultimate Learning Path
I structured the course like a collector’s roadmap:
Module 1: Valuation Foundations
- Greysheet decoding made simple
- Why NGC grades differ from PCGS (and why it matters)
- Spotting key dates before auctions close
Module 2: Auction Secrets Revealed
- My custom Heritage Auction scraper (students loved this!)
# Python snippet from actual course tools
import requests
from bs4 import BeautifulSoupdef get_auction_prices(coin_type):
url = f'https://www.ha.com/c/search-results.zx?term={coin_type}'
response = requests.get(url)
# Full script available to students - Building real-time price dashboards
