This is probably a bit different from the usual posts here but the principle is the same – buy underpriced, sell to the right buyer.
In Australia, state governments issued heritage number plates going back to the early 1900s. Some have become collectible – driven by patterns like repeating digits, sequential numbers, round numbers.
This guy hired a freelance Python dev to scrape the VicRoads database of 285K+ heritage plates, cross-referencing asking prices against recent secondary market sales to find underpriced combos.
The results 
- Bought 9 VIC plates from VicRoads at $12K each ($108K total) – sold for $304K. $196K profit.
- Best flip: plate 142.000 – bought $12K, sold $50.1K. 318% return.
- Quick flip: plate 234.345 – bought $30K, sold $43K in under a month.
Then a major catalyst hit: VicRoads stopped selling heritage plates entirely, making the secondary market the only source.
I’m currently holding 10 VIC plates bought for a total $198K. Estimating that I’ll be able to sell each plate for about $30K.
Total deployed: $507K AUD. Realised profit: $224K+ 
Not just him, either. A commenter confirms making “just shy of 6 figures” doing the same thing. Another says their 4-digit plate is now worth 20x what they paid for it 10+ years ago.
The universal takeaway here isn’t number plates – it’s data arbitrage using public databases.
Build a scraper to find underpriced items in a large public dataset, then resell on the secondary market.
Could work for domain names, vintage items, collectible cards, even real estate listings
