M4A4 Poseidon Minimal Wear is a Classified CS:GO skin that was put into the game as a part of the Operation Bloodhound Update on May 26th, 2015. The M4A4 Poseidon MW is a part of the Gods and Monsters Collection and its paint job depicts the battle between Pisces and the Greek God Poseidon. The M4A4 Poseidon is available in three different exteriors, them being Factory New, Minimal Wear, and Field-Tested.
In terms of value, the Poseidon is among the upper echelon of skins with its lowest exterior version usually selling for around $700. As the exterior quality improves, so does the price, heading upwards of $1000 for the Minimal Wear version of Poseidon and a lot more for the Factory New exterior. The M4A4 Poseidon doesn't have the ability to have StatTrak equipped which means that players won't be able to track their kill count on it.
