The Master Catalog

THE MERCH REGISTRY

What if every piece of music merch ever made had its own page? Every tour tee, every foil poster, every festival pin, every pressing — cataloged, numbered, and tracked. That's what we're building at M³.

Trading cards have it. Video games have it. Vinyl has Discogs. Music merch — the shirts you sweated through at Red Rocks, the poster you carried across a festival for three days — has never had a registry. Until now.

Every item in the registry gets a permanent catalog number. Catalog your own collection against it. Track prices across sales as the index grows. And when it's time to sell, your item is already linked to its history.

This is community-built. Fans, collectors, and vendors fill in the registry together — that's the only way it becomes something for everyone. Here's how you can help:
