Blue Tokens – Legacy Currency
Blue Tokens are a legacy currency that is no longer obtainable. As of now, unboxing duplicate skins from cases will no longer generate Blue Tokens. Instead, you can collect multiples of the same skin to use in Trade Up or sell them in the Community Marketplace.
If you receive a duplicate item that cannot be used in Trade Up, such as Epic or Legendary items, you can still sell them in the Community Marketplace.
Please note that Blue Token crafting from loadout was discontinued with the release of Update 1.46.
If you have some Blue Tokens lying around, you can spend them in the Blue Token Store, which is available for a limited time in Update 1.49. This is your final opportunity to use any Blue Tokens before they are permanently discontinued. After the store is gone, they are deleted from player inventories.
