American-Refined Gold From a US Mint Supplier
Sunshine Minting has supplied the precious metals mint industry since 1979, most of that time from Coeur d’Alene, Idaho before its 2025 move to Henderson, Nevada, and the company remains a longtime supplier of coin blanks to the US Mint. This bar holds one troy ounce of .9999 fine gold, sealed in Sunshine’s own assay card straight from the refiner.
A Sunburst Back, and a Disc You Need a Lens to Read
The front carries Sunshine’s eagle-over-a-rising-sun roundel, ringed by SUNSHINE and MINTING, with the weight, purity, and a unique serial number struck into the face. The back is covered edge to edge in a diagonal sunburst pattern, with a circular disc at the center. The disc hides an image, one that only shows up under Sunshine’s own decoder lens.
A Security Feature Most Refiners Skip
That disc is Sunshine’s Mint Mark SI, an authentication feature the company has built into its bars specifically because a hidden image is far harder to counterfeit than a stamped hallmark alone. Sunshine has also held ISO 9001 quality certification since 2010, the standard that governs how consistently its production process runs. The mark needs a lens, not visible under ordinary light.
Backed by the Refiner, Eligible for an IRA
Every bar ships new, sealed in Sunshine’s own assay card with a matching serial number, so a buyer can confirm a bar hasn’t been swapped or reopened before it reached them. At .9999 fine, it also clears the IRS’s minimum for a precious metals IRA. The serial matches the card, bar to packaging.

Sunshine Mint 1 oz Gold Bar FAQ
How can I confirm this bar is genuine?
Check the serial number on the bar against the number on its sealed assay card, and view the disc on the back under Sunshine’s Mint Mark SI decoder lens to reveal the hidden image. Two checks confirm it, the serial and the hidden image.
Where is Sunshine Minting based?
Sunshine Minting has supplied the mint industry since 1979, based for decades in Coeur d’Alene, Idaho before relocating to Henderson, Nevada in 2025. The company moved in 2025, after decades in Idaho.
Is the Sunshine Mint 1 oz Gold Bar IRA eligible?
Yes. At .9999 fine, it clears the IRS’s .995 minimum for a precious metals IRA with plenty of room to spare. Eligibility isn’t a close call, given how far past the floor it sits.
What does the Mint Mark SI actually do?
It’s a hidden image built into the disc on the back of the bar, invisible under normal light and only readable under Sunshine’s own decoder lens, making the bar harder to counterfeit than a stamped hallmark alone would. The image stays hidden, until viewed through the right lens.
What condition does it ship in?
New, straight from the refiner with no handling in between. Condition is new, not a numeric or third-party grade.
