The more modernized gear generally has a greater value for trade regardless of whether it has low requirements (like the FB sorc's shield) or a very high stat variance (like the eth titan weapons). The latter are less valuable from upgrading due to the need to roll for a perfect version.
Recycle Points
The item upgrade upgrader allows players to upgrade their gear by transferring the currency to an NPC. Upgrades can be applied on any type of armor or weapons. However, the item upgrader mod that is used for the upgrade will be consumed for the duration of time and will not be able to be used again. Upgrades can also be used to create enchantments.

Upgrades will cost more, based on the level of the item but they will always be cheaper than purchasing new gear. For instance, upgrading a Benthic chest to ilvl 385 will cost 20 recycle points while buying a similar item from a different player will cost 105.
Valorstones
Upgrades are items that can be used to upgrade tools, armor, weapon and accessory upgrades. Players can purchase them from NPCs of item upgraders for a variety of currencies. They can also find them on random treasure lists. Once purchased, an upgrade is able to be used on any weapon, tool or armor. button, which will display an item's preview at its next upgrade level in the event that the player has enough materials.
The cost of upgrading varies based on the slot for the item and the current item level. For instance weapons are more expensive than bracers, or gloves. Each step costs 15 Flightstones plus a set number of crests. Some upgrades offer discounts on Flightstones. Once an item is upgraded to a certain degree it is able to be degraded and returned to the upgrader for a lower amount of the two currencies.
A lot of locations offer upgraders for items, including the main Island and a few outposts. The NPCs provide both an upgrade coupon as well as the possibility of getting the latest recipe. The discount on upgrades increases as more items are upgraded. It can also be increased by having players complete certain achievements or quests.
Icewind Dale does not have an item upgrader at start unlike Cromwell from Baldur's gate II. Instead, the NPCs that can be used to upgrade are acquired via several methods, which is both an improvement and a drawback.
In Season 3, many new features have been added to the upgrade system. After an upgrade has been completed to a specific level for an armor slot, upgrading other items to the same item level, will cost less. This applies even if the items come from another set of gear.
The amount of Valorstones required for upgrades is decreased, and the discount is account-wide. The amount of Harbinger Crests needed to upgrade is reduced as well, but is only available when certain milestones have been reached.
Crests
Players have a number of choices when it comes to upgrading their gear in WoW. Flightstones are a currency that is available to everyone who wants to upgrade. Crests are more special, and are used during specific item level upgrades. Crests are an integral part of the Dragonflight Gear Progression System introduced in version 10.1. They come in four ranks.
First, you should know that the crests can only be purchased for equipment that is that is of a particular rank. Each rank has an upgrade path that is different. The simplest and simplest upgrade process costs just 15 crests while the most complex can require as much as 20 crests, based on the type of equipment that is being upgraded.
Players can earn crests by working through content that is of the appropriate level, whether that means walking around and doing outdoor activities for lower-tier gear, dungeons or raids of any difficulty for higher-tier items, or Mythic+ dungeons or heroic raid bosses for gear that is used in the endgame. These crests are then exchanged with an Item Level Upgrade upgrader like Cuzolth or Vaskarn, in Valdrakken to upgrade the item in the proper steps and paths.
The new currency system isn't complicated to use, but it will bring some changes to the upgrade process. Once a piece of gear has reached the highest level of upgrade for any rank (Explorer or Adventurer) it is no longer required to purchase Flightstones. This change is intended to allow players to get their gear up to the highest ilvl possible on all their characters rather than relying solely on seasonal loot.
Another significant modification is that crests have one usage and it's crucial to use them wisely. It's Best item upgrade to use your Whelpling-rank crests on the best gear that you can find, and save Drake and Wyrm Crests to be used for the next set of upgrades. This is particularly applicable to items like rings and trinkets that occupy multiple slots. The discount for the entire account is only applicable when all slots on the character are filled with high-quality equipment.
