An ultimate prize for the advanced collector, this well-presented
example of the coveted 'Gold Cas' stands as a magnificent
crypto-era artifact-an essential highlight in any serious cabinet
of physical cryptocurrency.The "Gold Cas" was the first gold coin funded with cryptocurrency and the highest denomination coin produced by Caldwell. At the time of introduction they could be purchased directly from him loaded with 1000 BTC for $5,500. It is estimated that just 5-7 coins were made with one private key, and an uncertain number, presumably around twenty, were issued with the 2-factor authentication as seen here. The 2FA password will be available to the new owner of this lot.
