Create a photorealistic, fictional, circular coin based on the provided image.

Create a photorealistic, fictional, circular coin based on the provided image.
Core Transformation Requirement:
Bas-Relief Sculpture: This is the most critical command. Masterfully convert the input portrait into a metallic bas-relief sculpture for the coin's obverse (heads side). All features—facial contours, hair strands, and clothing folds—must be translated into sculpted forms with physical depth and dimension.
Physical Properties & Material:
Metal Choice: Define the coin's material as [Choose one: Aged silver with circulated wear / Polished gold with micro-scratches / Ancient bronze with green patina]. The metal surface must exhibit realistic specular highlights and shadows.
Sense of Weight: The overall visual should convey a heavy, solid, and substantial feel.
Coin Design Elements:
// Here, the text behind the text is the text content of the custom coin
Legends (Text): Engrave clear text along the raised rim of the coin.
Upper Text: A fictional country name, e.g., "REPUBLIC OF CHRONOS".
Lower Text: A year and denomination, e.g., "100 CENTS • 2025".
Rim: The coin must have a distinct, raised rim, optionally detailed with denticles.
Field: The flat background behind the relief should not be a perfect mirror but should show faint, radial mint luster or fine scratches from circulation.
Realism & Aging Details (Crucial for Authenticity):
Minting & Machining Marks: Simulate the manufacturing process by adding subtle die polishing lines or minuscule striking imperfections on the field.
Natural Circulation Wear:
High-Point Wear: The highest points of the relief (e.g., cheekbones, tip of the nose, highest strands of hair) should appear brighter and slightly smoother than the recesses, mimicking the effect of long-term handling.
Patina: A darker layer of oxidation or grime must be settled into the recesses of the relief (e.g., eye sockets, between hair strands, inside letters), which dramatically enhances depth and realism.
Scratches & Dings: Add random, naturalistic micro-scratches and slight dings on the coin's surface and edge.
Photography & Presentation:
Macro Photography Style: The final image must be a sharp, highly detailed macro photograph.
Lighting: Use dramatic, angled, single-source lighting to cast sharp shadows, maximizing the visibility of the relief's contours and the metallic texture.
Viewing Angle: Present the coin from a slightly angled top-down perspective rather than a flat, direct overhead shot, to better reveal its thickness and relief details.
