The release story
Maker statements and surviving thread evidence, organized as one continuous record.
Keys, serials, and funding
One private key per coin
As with the silver cents, 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.
Serial ranges
The 25 matching six-coin sets drew random numbers 1–50. Regular-silver singles defaulted to serial no. 51 and above.
Funded or BF-marked
Buyers could provide exactly 0.1 BTC before shipment or receive a coin marked “BUYER FUNDED.” PGP-signed address lists were promised for both sets and singles.
Presentation and variation
Every coin included its own COA and capsule. The post warned that rainbow production could produce visible color differences from the samples.
The one-ounce Double Rainbow error
All known gold-select rainbows affected
The gold-select process obscured the first rainbow treatment on the one-ounce version just as it did on the smaller cents.
Retroactive second treatment
The maker added rainbow elements to the front and reverse again where possible, creating the “double rainbow” description while preserving the finish as an acknowledged error. He warned that alignment could vary and that ghost-like remnants of the first treatment might remain visible beneath the second.
Two certificates
Each affected dime was to ship with its normal certificate and a separate mint-signed error certificate.
Distinguishing regular Gold-Select
Smoothie said the regular Gold-Select pieces looked very similar, but their reverses lacked the additional texture or ghosting present on the rainbow-error version.
Buyer decisions before finishing
Customers were asked whether they wanted the rear tribal rainbow, the separate error certificate, and an “ERROR” marking on the hologram. The hologram marking was an all-or-none decision for the affected group rather than a mix of marked and unmarked pieces.
Funding status reconfirmed
Each buyer was asked again whether the coin would be funded. Unfunded pieces would receive the “BUYER FUNDED” hologram marking.
Not a new mintage
The error treatment describes the existing rainbow gold-select allocation; it is not an additional coin type above the stated 50-piece maximum.
Error finishing and delivery plan
Eighteen to twenty days
The posted estimate allowed seven to nine days for the second rainbow treatment, about four days for the mint-approved error certificates, and about seven days for the maker’s normal finishing work.
Target mailing window
The resulting target for USPS delivery to the carrier was February 27–March 1, 2023, or sooner, for orders containing the one-ounce rainbow Gold-Select error version.
Regular Gold-Select schedule
Orders containing only the regular Gold-Select version, with no pending rainbow Gold-Select pieces, were estimated to ship within ten to fourteen days.
