How we track what nobody else does.
The stock market for
nostalgia
Millions of retro items change hands every day — but unlike stocks or crypto, there's no live price index. No way to know if that Walkman is a deal or a ripoff. Until now.
Built in the Netherlands. Tracking 290+ collectibles across Europe — daily.
Live prices, not sold prices
Other sites show what something sold for last month. We show what it costs right now — based on active listings that are live today across the European secondhand market.
AI-assisted, human-curated
Every item is individually tuned. A taxonomy engine with 3,000+ rules automatically filters junk — wrong editions, parts, bundles, and fakes. What's left is the real market.
The whole market, one price
We monitor the European secondhand market daily. The median price reflects real supply and demand across borders — not just one country or one source.
Items nobody else tracks
Zelda CD-i games. Thunderdome vinyl. Vintage tracksuits. A sealed Akira VHS. These items have real value — we're building the price record that didn't exist before and can never be backfilled.
Data that compounds
Every day we collect, the index becomes more accurate. Price trends emerge. Seasonal patterns appear. Historical data can never be recreated — every day we don't collect is lost forever.
Built in the Netherlands
Born from Dutch secondhand culture — flea markets, thrift stores, and a deep appreciation for things that last. Expanding across Europe, one collectible at a time.
Tracking retro collectible markets across Europe since 2025.
