Coins are items found when opening Chests or killing other players and Orcs and crates. Coins serve as currency in the game, which you can use to purchase weapons, hats, and shields. Most commonly, players drop a value of 1-3 coins, but you will more often receive 3 coins from those who have more bones, and/or are higher up in the In-Game Leaderboard, than others. There are 3 types of coins, each with a separate value.
In order to be able to spend coins on Weapons, Hats and Shields in the Armory, you need to be logged in.
Players are only allowed to collect 1200 gold a week. The gold cap goes down by 300 every day, so in 96 hours you can farm 1200 gold again.
Gold Coin
The Gold Coin is worth 3 coins and is the most rare. It usually only drops from high ranking players, or from Chests. Trading with the gold stalls will give you one gold coin. Gold stalls have been removed from the game instead you can get coins from Orcs, crates and players.
Silver Coin
The Silver Coin is worth 2 coins and is more common than the Gold Coin, but more rare than the Copper Coin. You may come across it when killing average players, however it is the most common coin when opening Chests. Breakable Chests have been removed from the game as of the Winter Survival update.
Copper Coin
The Copper Coin is the most common coin, and is only worth 1. You can acquire the coin from killing any player, and it will drop from Chests. With the addition of the Winter Survival, it is now obtainable from Orcs and crates.
You can see your coins in game at the top of the screen
