The release story
Maker statements and surviving thread evidence, organized as one continuous record.
Maker clarifications from the auction
One of one
Smoothie repeatedly described serial no. 100 as the only 2012 5 BTC brass Lealana–Casascius hybrid he would assemble and sell.
Off-center hologram
The placement reflected the Lealana blank’s recess. He offered to rehologram it more centrally for the winner, but warned that it would no longer carry serial no. 100 and still could not be perfectly centered.
Funding requirement
The maker wanted the unique piece funded so a later purchaser would not mistake an apparently intact coin for a funded one. He allowed the winner two weeks to provide the 5 BTC face value after the auction.
Regulatory discussion
The thread records smoothie considering, and ultimately doubting, the use of a trusted third-party escrow to fund after delivery because of address-error risk and uncertainty under U.S. money-transmission rules.
