What's the error?
public address?
The hologram says 'Casacius' instead of 'Casascius' (the text on the background).
but I see that there're 9 letters on the picture...
background = blury part that's hard to read
foreground = the 9 letters you see
I recommend buying the Encyclopedia of Physical Bitcoins and Crypto-Currencies
Just got this Encyclopedia of Physical Bitcoins and Crypto-Currencies. It's gorgeous.
Thanks s lot for the info.
