S2 100 BTC 2011 Bar


Like its predecessor, the series 2 bar comes stamped with ‘100 BTC’ below the hologram. This bar had the largest production of the denominated Casascius bars, with the most unopened specimens still remaining. The photo on the left demonstrates the plain polished back of a bar that is still in its original plastic wrap. All Casascius bars are identical on the back with a smooth brass surface.
