Thread: Item List - Street value

Well its your lucky day.

blue shards 400 crowns each
sword-stones anywhere from 1k-1.5ke
silver coil 3k-5k ( rare)
force dynamo-1.1k
fine fabric-1k

EDIT:
0 star (shards): 100cr each blue 300. All very common, but used in every craft.
1 star: 100cr - 300cr each. No rares here, and most aren't used for every craft.
2 star (common/unused): 500cr each.
2 star (rare/popular): 1000cr each. High demand, low stock, and some are rare aswell. This would be, for example, Swordstone or Monster bones.
3 star (common/unused): 2000cr each.
3 star (rare/popular): 3000cr each. Certain materials such as Drake Scale or Critter Carapace are quite rare, thus worth a lot.
4 star (general?): 4000cr - 5000cr. Four star materials are currently in low demand, and most of them have about the same drop rate aswell, so they're all about the same price.
5 star (common): 7500cr - 10000cr. Only drops in T3, which can be difficult to get to and complete. Demand is low.
5 star (rare): 15000cr - 20000cr, possibly more.
