Google 1998記念コインのフォトリアリスティックプロンプト

A high-resolution photograph of a gold coin featuring the Google logo at the center. The coin should have the year 1998 engraved at the top. Include finely detailed engravings, ornamental border patterns, and authentic coin textures like reeded edges, matte background, and polished raised elements. Add inscriptions of 'Google' near the bottom in bold lettering. The design should look like a professionally minted commemorative coin with symmetrical layout, precision detailing, and classic metallic shading, presented on a dark backdrop for contrast.
