Built for collectors,
by collectors
Tesoro Track exists because we got tired of manually searching eBay every time we wanted to know what a set was actually worth. So we built the tool we always wanted.
Real eBay Sold Data
Every price on Tesoro Track comes from actual completed eBay sold listings — not asking prices, not estimates. When you see an average sale price, that's the real money that changed hands for that exact item. We pull data daily so you're never looking at stale numbers.
What We Track
We currently track Mega Construx (Halo, Pokémon, Call of Duty, Masters of the Universe, Destiny and more), Funko Pop figures across all major licenses, and LEGO sets including Icons, Technic, Star Wars, Harry Potter, Ideas, and Architecture. More categories are coming soon.
How Prices Work
Our average sale price reflects the median sold price from the last 90 days of eBay activity. We remove outliers (suspiciously high or low sales) to give you a realistic market price. Prices are broken down by condition — New Sealed, Open Box, and Used — because condition matters enormously in the collector market.
Portfolio & Watchlist
Your portfolio and watchlist data is stored locally in your browser right now — no account required. We're working on cloud sync and user accounts so your data follows you across devices. For now, your data is private and never leaves your computer.
Free Forever
Core price tracking is free and will always be free. We're building premium features for power collectors — unlimited portfolio tracking, price history exports, email alerts, and advanced analytics. But the fundamentals? Always free.
