Unverified Steam Deck Prototype Sells for $2,000 on eBay

The engineering sample, marked 'not for resale,' features unique design elements but remains unconfirmed by Valve.

A Steam Deck prototype labeled 'Engineering Sample 34' was sold on eBay for $2,000 on April 8, 2025, down from its initial $3,000 listing price.
The device differs from retail models with circular track pads, blue triggers, and a missing right joystick, and it lacks an installed operating system.
Valve has not commented on the sale or the authenticity of the prototype, leaving its legitimacy uncertain.
The original eBay listing is no longer accessible on the platform but can still be found through third-party tools using eBay's API.
This incident highlights challenges in verifying rare tech items in secondary markets and raises questions about the resale of unreleased hardware.
