Someone at Valve loves throwing Steam Controller prototypes into charity bins, as another prototype gamepad has ended up at Goodwill. If I had a Steam Machine for every time this has happened so far, I'd have two more than I currently have, but as someone who thinks the storefront giant should have stuck to its stickless design, I'd be thrilled to find one of these oddball touch controllers in the wild.
The story behind this Steam Controller prototype feels like Deja Vu, was highlighted by Waste-Set5032 on the same Subreddit seven years later (via Videocardz). This time, the Redditor says the pad was found by their father in Seattle, who has also chimed into the thread to confirm they grabbed the important piece of Valve hardware history.
