Collection: Casascius XV

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, I didn’t want that anniversary to pass unnoticed.

So I created Casascius XV, a Finite by Design tribute to the physical Bitcoin that helped start it all.

15 years. Two metals. 15 of each.

Offered in parallel Brass and Stainless Steel editions, Casascius XV draws directly from the unmistakable visual language of the original Casascius coins, reinterpreted through Finite by Design.
