The Lutece Coin is a small, intricately designed coin with a distinct Art Deco aesthetic, featuring a smooth, polished metal surface with a slight golden sheen. The obverse side displays a finely engraved portrait of Rosalind Lutece, surrounded by ornate geometric patterns, while the reverse side shows a series of interlocking gears and quantum symbols, hinting at its steampunk origins. The edges are slightly worn, suggesting age and frequent use, with a subtle luminescence that gives it an otherworldly glow.
