This month marks the 15th anniversary of Casascius Physical Bitcoins.
I didn’t want the anniversary to pass uncelebrated, so I created Casascius XV, a small Finite by Design tribute to the physical Bitcoin that helped start it all.
15 years. Two metals. 15 of each.

COMMISSIONED COLLECTION
Over the years I’ve created a handful of one-off pieces for individual collectors. Some started with a completely original idea, while others became unique interpretations of existing Finite designs.
I’ve now brought those pieces together in the Commissioned Collection.
HODLkorn is the newest addition, joining Ad Astra, CSV | Stainless Steel Edition, and NightWatcher in the permanent Finite Archive.
Each is a 1 of 1, created for a specific collector and already in its permanent home.

Another test run for number 0 of the Block Zero line. This testing is on a 25mm cube (actual production will be on 35mm cube) so everything is a little smaller and doesn’t work quite as well. Productive test nonetheless. This thing is going to be beautiful when competed.
