Sunstock operates a single retail precious metals store in Sacramento, California, trading under the name Mom's Silver Shop, which it acquired in 2018. The store buys and sells gold and silver coins and bullion, serving retail investors and collectors seeking physical exposure to precious metals. Sunstock's business model is built on the spread between acquisition cost and resale price across each transaction. Profitability is driven by transaction volume and the margin earned on each coin or bar. Sunstock also holds physical metal inventory directly on its balance sheet, meaning its asset values fluctuate with spot prices for gold and silver. A key goal is to become an Authorized Purchaser of bullion coins from the U.S. Mint, which would allow Sunstock to buy coins directly from the Mint at a discount to current acquisition costs, improving margins — though no timeline has been provided for when Sunstock might qualify.
