The release story
Maker statements and surviving thread evidence, organized as one continuous record.
Keys, serials, and funding
One private key per coin
The private key was sealed beneath the coin’s hologram and could be accessed only by peeling it. Paper or digital certificates carried the public Bitcoin address, serial number, and identifying coin details. Public addresses and serials remained visible on the reverse.
Serial ranges
Matching six-coin sets were randomly drawn from serials 1–139. Regular-silver roll pieces defaulted to no. 140 and above.
Funded or BF-marked
Buyers could fund the exact 0.01 BTC address before shipment or receive an empty coin whose hologram said “BUYER FUNDED.” PGP-signed address lists covered rolls, sets, and singles.
Miniature presentation
Every piece included a capsule and a certificate styled after the 2013 certificates at roughly half their size.
The Double Rainbow error
What failed
Gold-select plating obscured most of the intended rainbow on every rainbow gold-select cent known to the maker, leaving only ghost-like traces.
Why “double rainbow”
After the original rainbow was lost during plating, a second rainbow treatment was added where possible. The maker therefore named it the “DOUBLE RAINBOW ERROR COIN.”
Two certificates
Affected coins received the normal certificate plus a separate mint-signed error certificate documenting the finish problem.
Same problem in both sizes
Smoothie confirmed that the production issue affected both the one-tenth-ounce cents and the one-ounce dimes.
Sales and fulfillment timeline
First-party updates posted by smoothie, arranged chronologically.
Sales opened
Seventy matching six-coin sets, regular rolls, and five special single finishes were offered.
Six-coin sets sold out
The public count fell from 19 to zero in four days.
Remaining singles closed
The maker marked the remaining special singles sold out or retained for his personal collection/future auctions.
Error treatment documented
The Double Rainbow explanation and two-certificate plan were posted after the gold-select coins arrived.
