Ancient Roman-style coin with two faces (Janus) on a weathered, patinated surface, surrounded by glyphs.

Create an ancient Roman-style coin featuring a single head with two realistic, connected faces (a Janus figure), sharing one neck. The coin should have a weathered, cracked metal surface with a greenish-blue patina. Surround the central head with a ring of glyphs, blending sharp angular strokes and swirling mystical curves. Add a faint glowing third eye between the two faces and etch arcane runes subtly into the coin’s background. The edges should be slightly irregular, hinting at ancient hand-forging. Set against an aged, eerie, and regal atmosphere with subtle magical shimmer. Add the word "Janus" at the bottom of the coin. See more
