Released three months after the series 1 ‘Error Bitnickel’ was offered for sale, this is the ‘true’ Bitnickel featuring a
silver (or nickel) tone hologram. Interestingly, less of these were
made than the series 1 versions.
On August 18th, 2015, six additional 5 BTC coins were funded by Casascius. These had been fully paid for and delivered
years earlier, but funded much later. It is unknown who owns these notable late-funded coins.
