Around 2009-2010, some players thought of the rune spear as a valuable item due to the there having been a very low number of players fighting monsters which drop them. After many players left Classic for considerable lengths of time, the rarity of the Rune Spear and lack of new stock coming onto the market had inflated in price. The remaining community thus gave it a rough price of around 10 million coins.
As of 2017, many more players are fighting high level monsters, but the rune spear is still not a commonly traded item. Sometimes offers can go as high as 1 million coins, but due to low demand, the perceived value of a rune spear is not high.
