This coin was released in December 2011, when the total price of the coin, including the 1,000 BTC, was only about 5,000
USD. The Casascius 1,000 BTC coin was the first gold coin funded with crypto-currency.
The coin pictured is the only one known to be funded in 2011, discounting the prototype coin. It is not known if it is the only
series 1 gold coin. The first-bits for this coin are laser-engraved on the upper part of the hologram, making it impossible for the address to be manipulated. As with the prototype, ‘laser rimming’ is not utilized for this coin.
