Unfunded Casascius Private Key Insert. Firstbits 1CswV6pi. Genuine (ICG).

Significant Unfunded Casascius Private Key Insert Only The Second Example We Have Handled Unfunded Casascius Private Key Insert. Firstbits 1CswV6pi. Genuine (ICG). Unfunded and non-loaded. An absolutely fascinating and elusive artifact from the Casascius series that represents just the second such specimen we have handled. This is an actual unused private key insert originally intended to be used on a funded coin. Seldom seen in private hands, it offers a glimpse at the infrastructure behind these prized Physical Bitcoin issues. On the front of the insert is the 8-digit Firstbits code that can be used to verify the public address and funded status. This Firstbits code is generally visible on assembled coins through the clear viewing window of the tamper-evident hologram sticker. On the back of the insert is the private key that can be used to redeem the coin and add the associated funds to a digital wallet. It is certainly an irresistible offering for the advanced Casascius collector.
