Know what your collection is really worth.
Diecast-o-meter keeps your cars in a clean photo grid and checks real eBay sold prices. You tick the listings that match your car — so every value is one you can trust.
How it works
Add your cars
Snap or paste a photo, pick the brand, scale and year. Import a spreadsheet if you already keep one.
Check sold prices
One click searches eBay’s sold listings for that exact car — from your own browser, with our free helper extension.
Approve what matches
Tick the listings that are really your car. The median becomes its value, with the date it was checked.
No guessing, no AI
Every value comes from real sold listings you approved. Wrong matches are remembered and hidden next time.

Everything a collector needs. Nothing they don’t.
Two boards
Your collection, and the cars you’re hunting — with target prices and a “deal” badge when eBay drops below it.
Prices that stay honest
Values go “outdated” after 90 days (you choose), so you always know which numbers are fresh.

Questions
Where do the prices come from?
From eBay’s sold listings (the last ~90 days) and current “for sale” listings. You choose which listings match your car; the estimate is the median of those.
Why is there a browser extension?
eBay doesn’t offer sold prices to apps like ours. The free helper opens eBay’s sold search in your own browser, reads the results and passes them to Diecast-o-meter. It never buys, bids or posts anything.
Which brands and scales work?
Any. Hot Wheels, Matchbox, Mini GT, Tarmac Works, Majorette, Greenlight and more come preset, and you can add your own brands, scales and categories.
Can I bring my existing list?
Yes — download the CSV template, fill it in (or export from your spreadsheet) and import it.
