Can You Sell Artifacts in God of War Ragnarök?
Although it may seem like a bad idea to do so, you can and should sell the Artifacts you collect in God of War Ragnarök. Doing so will not negate any completion progression and will reward players with solid amounts of Hacksilver. Hacksilver is the in-game currency of God of War Ragnarök and is key to acquiring useful items as well as upgrading armor and weapons.
It may seem enticing to keep all of the Artifacts you've found in your inventory, but doing so will not reward you in any way. Once collected, Artifacts serve no other real purpose than to be sold making it best for players to take advantage of the Hacksilver they can get for them at shops.
