Rocket League players will soon have a use for all those duplicate items

Following the update, players will be able to trade in five duplicate “Uncommon” or “Rare” items at a time, to get one item of the next-highest quality.

“Some items, like those with ‘Painted’ or ‘Certified’ attributes, may become much more valuable if you can trade them to other players.

These items will follow the same drop rules as Uncommon items.
