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.

2013 0.5 BTC Series 2 0.5 BTC 2013 ‘Void Coin’
These coins were given out to the press as gifts. They are different than typical 0.5 BTC Brass coins in that they have no public or private key, but instead display a repeating “VOID” in the window. These were shown in the movie The Rise and Rise of Bitcoin and were custom made in order …
2013 0.5 BTC Series 2 0.5 BTC 2013
On February 17, 2013, Casascius released these coins saying “This is being added due to the rise in bitcoin value”. The price of Bitcoin had risen from under 14 USD to nearly 30 USD within a couple of weeks. As with the 2013 series 2 1 BTC coins, there is a ‘lobe’ on the private …

This coin is identical to the 2011 version, except the year ‘2012’ is displayed on the front. A significant number (nearly a fourth) of these coins have been redeemed, most likely as a direct result of the dramatic rise in bitcoin value in late 2013. *The numbers refer to series 2 1 BTC coins funded …
2011 1 BTC Series 1 1 BTC 2011 ‘Demo Coin’
These are the first experimental coins made by Casascius. They were used to test the holograms to reveal the honeycomb pattern left behind, without ever being funded. The coins can be identified by looking up the public key on a peeled, seemingly ‘pre-funded’ coin. If no BTC has ever been in the address, then it …
2011 1 BTC Series 1 1 BTC 2011 ‘Double Error’
These five coins are distinctive in having the first bits, which are usually in the middle of the hologram, printed 3 mm higher than normal. The specific coins and even load year are unknown, but they are all series 1 1 BTC 2011 ‘Error’ coins, making these five the rarest of the already sought-after variety. …
2011 1 BTC Series 1 1 BTC 2011 ‘Error’
Announced on September 6th of 2011, these coins were the first funded physical Bitcoins ever produced.
