An item can have different market values if it is from a Series or not.Item Prices (all origins) shows the combined value for each item from its Series and Non-Series variants.
Item Prices (not from Series) and Item Prices (from Series) show the value for applicable items without or with Series.Five Non-Series items from any rarity can be traded up to an item of the next higher rarity. This gives them a basic value even if a specific item has low demand by itself. Only Non-Series items can be traded up like this. Items from Series can't be traded up at all.Many of these Non-Series items get traded in bulk at an average base price for tradeups. You can see these average Non-Series prices here on the prices page too ("Generic Non-Series Items" above price tables).This does not mean that for example every NCI has exactly that value. Specific demanded items can always be worth more. These NC prices rather give the according items a minimum value if they are not from a Series.You can start a trade-up simply by selecting an item in your inventory:Tip: you can see the potential rewards for your trade-up here on this page too: just filter for and the according rarity, eg .Blueprint values are calculated based on Series Item prices and crafting cost. For Blueprints that are mathematically worthless (crafting cost higher than item market value), we display greyed-out symbolic values that buyers are willing to pay in rare cases. We will keep monitoring the blueprint market closely and adjust this system if market behavior changes in the future for any reason.
