Maker clarifications from the auction
Final one-of-one decision
The opening language contemplated one or possibly two hybrids, but smoothie then made a final public decision that this 2011 Casascius 1 BTC brass type would have exactly one assembled and sold example.
Serial and placement
The completed hybrid was Lealana serial no. 77. Its gold Casascius hologram was deliberately off-center because the recess geometry of the Lealana blank differed from a Casascius coin.
Delivery state
Smoothie explicitly stated that the coin was sold unfunded and unloaded.
Responsibility for the key
Because his hologram covered the key, smoothie said responsibility for the key’s security and authenticity rested with him under Lealana’s terms, not with Casascius.
