M4A4 Howl Minimal Wear is a CS:GO skin that was added to the game on May 1st, 2014 as a part of the Hunt Begins Update and features a black paint job with red accents and a wolf painted on the side. The skin has attained legendary status due to controversy and ever since was removed from the game and can no longer be obtained by any means other than trading.
How much is an M4A4 Howl Minimal Wear? There is no easy answer to that question. Since the M4A4 Howl is the only skin of Contraband quality, it is extremely rare and very rarely pops up for sale. However, when it does, the Minimal Wear Version can be worth over $5000.
As for what would be a good trade for the M4A4 Howl Minimal Wear? Well the M4A4 Howl will only get more expensive and is a good investment, but if you are hellbent on trading it, you could get almost any other CS:GO skin for it.
