Captain Olimar's Journal
"This rare, alien metal doesn't exist on Hocotate. When I gaze at it, I'm gripped with an overpowering sense of greed. On Hocotate, there is a valuable metal with a stunning sheen that has a similar effect. Perhaps this alluring metal is responsible for many of this planet's woes."

Sales Pitch
"Such radiance! Such shine! Like magic, this product stimulates greed in all intelligent life-forms. Bring your wallets and gather around, buyers!"

Trivia

 * Although Olimar states that the coin's metal (gold) is unknown to Hocotate, the Ship says it is clad in gold after repaying the debt.
 * This treasure weighs the same as the Mirrored Element, despite gold weighing more than silver.
