Build one mobile finance app icon around the Central Symbol. Use a standard iOS and Android rounded-square shape with a full-bleed Primary Color background and no inner border or frame. Render the symbol large and centered, filling roughly 60 to 70 percent of the icon with even padding, a confident silhouette, and clear readability at 48 pixels. Apply a subtle 3D treatment using the Secondary Color for restrained dimensional shading and a soft bevel, with gentle directional light and a very soft shadow. Keep the design clean and uncluttered, using no more than three colors plus white. Show the icon alone, centered on a plain neutral background with a soft cast shadow. No extra text, labels, brand logos, trademarked characters or watermark.
Use these details:
Central Symbol: "a simple dollar coin with one centered dollar sign"
Primary Color: "emerald green"
Secondary Color: "soft metallic gold"
