2,028 x Mahogany plank (4,279,080)
Making mahogany planks at the Sawmill is a decent way to make money. Each plank requires one mahogany log and 1,500 coins. The fastest way to get to the Sawmill is through the Balloon transport system, which requires completion of Enlightened Journey. Once you've unlocked the Varrock route, requiring 40 Firemaking, you can fly to the Varrock balloon, just steps away from the Sawmill, for one willow log.
Start out in the Castle Wars lobby, and withdraw 26 mahogany logs, one willow log, and at least 39,000 coins. Run north out of the lobby and north to the balloon, and fly to Varrock. Run north to the Sawmill operator, and select Buy-plank, and then Buy All under the mahogany logs. Teleport back to Castle Wars with a Ring of dueling, bank, and repeat the process.
