Exchangeable item

An exchangeable item is a category of item which serves no in-game purpose aside from being able to be traded for another item or some sort of service. Though several Key Items fall under this category (such as Generation I and 's Bike Voucher), their exchange is often important to the story of the games, so they are not included here. These items are often also valuable items.
