The Mandelbrot Set is one of mathematics' most famous fractals. Defined by the simple equation zₙ₊₁ = zₙ² + c, it reveals infinite complexity—every zoom uncovers new patterns that echo the whole, with no end to its detail. It's a striking example of how simple rules can create extraordinary beauty.

This coin captures that iconic fractal in solid brass. Precision machined and then deep laser engraved, the center is hand-filled with black resin to create a bold contrast that highlights the intricate geometry. A piece that blends mathematics, craftsmanship, and timeless design into a pocket-sized work of art.
