Our commitment to quality is unmatched in the industry. These pieces are a combination of physical bitcoin, pure bullion, and limited edition art pieces by presidential sculptor, John B. Andelin. We are continuing to take physical bitcoins to the next level! Each coin is personally signed by the artist and sealed in a tamper proof casing. Each coin is also embedded with physical bitcoin, with private key engraved on the edge, out of view unless sealed case is broken.
Each coin has bitcoin securely embedded as "cold storage". In other words, after coins are engraved, further records of private keys are destroyed. Private keys have all been generated using an offline bitcoin client and have never been transmitted over the internet, nor do they exist on a device connected to the internet and never will. For reference, the public address is located on the reverse side of the medallion, and the private key is located on the edge of the coin. Each coin is sealed in a tamper proof case which hides the private key unless the case is intentionally broken. Furthermore, a proprietary cypher system encodes the validity of each case and can be used to authenticate the coin to its case. A certificate of authenticity is included with each coin and has been signed by company officials. All public keys issued on our coins will be published online for all to see and verify the inclusion of the bitcoins. Alitin Mint also provides a verification service to validate cyphers contained on each case.
