Casascius XV | Brass Edition

15th Anniversary Tribute · 2011-2026

In September 2011, Mike Caldwell offered the first Casascius Physical Bitcoins for sale, helping establish what would become the world of physical Bitcoin collecting.

Fifteen years later, Finite by Design created Casascius XV to make sure that anniversary did not pass unnoticed.

Laser engraved in brass, Casascius XV draws directly from the unmistakable visual language of the original Casascius coins while incorporating Finite by Design details throughout. The reverse is secured with a Finite by Design tamper-evident hologram and carries three concentric rings of binary, a nod to the design language of the original.

The Brass Edition consists of just 15 individually numbered pieces, 01/15 through 15/15.

A separate Stainless Steel Edition of 15 pieces is also available, featuring selective MOPA color treatment.
