Value

Every item in RuneScape has a static value in coins predetermined by Jagex. This value is used in the following features in the game: Note that this value stands apart from fluctuating Grand Exchange prices that items may also have.
 * High Level Alchemy - Equal to $$\lfloor \frac{3}{5} V \rfloor$$ where $$V$$ is the value.
 * Low Level Alchemy - Equal to $$\lfloor \frac{2}{5} V \rfloor$$ where $$V$$ is the value.
 * Items Kept on Death Value - All untradeable items use the value as their Items Kept on Death Value. Prior to an update, all items used this value.
 * Daemonheim Price Checker - All items in Daemonheim show their value by using the Price Checker.
 * Store Prices - Prices in shops are based on an item's value.
 * Items that drop coins in their place - For the items that are replaced with coins at a gravestone (Barrelchest anchor, Korasi's sword, Veteran cape), the amount dropped is equal to the value.

Finding an item's value

 * For untradeable items, opening up the Items Kept on Death interface with only that item shows the value.
 * For Dungeoneering items, opening up the Price Checker shows the value.
 * For tradeable items, the high alchemy price $$\times \frac{5}{3}$$ will give the value, so long as it is not rounded down.
