USP-S Orion Minimal Wear is a Classified pistol skin that was added to CS:GO back in May 2014 as a part of the Hunt Begins Update. It is a part of the Huntsman Collection and can no longer be obtained by opening the Huntsman Weapon Case due to its creator being involved with the M4A4 Howl controversy, however, it is still in circulation and can be obtained by purchasing it from the market, or trading up to it. The USP-S Orion can come in all five exteriors and can have StatTrak technology attached to it.
When it comes to value, the prices of the USP-S Orion skin can differ a lot depending on the exterior of it as well as StatTrak. The better exteriors such as Factory New and Minimal wear usually go for around $25, the Battle-Scarred variant of it can fetch two times as much. The same applies to its StatTrak counterpart.
