Golden State Mint (GSM) is a private mint based in Southern California that produces .999 fine silver rounds, bars, and fractional silver. GSM is one of the more widely carried private mints among online bullion dealers, and their products are competitively priced against other generic rounds and bars. FindBullionPrices tracks GSM products across multiple dealers so you can compare premiums and find the lowest price on the specific round or bar you want
Rounds are GSM's core product. Their most popular designs include the Buffalo round -- a .999 fine version of the classic Buffalo Nickel/Indian Head design -- and the Aztec Calendar round, which features the Aztec sun stone on the obverse. Both are available in 1 oz and fractional sizes (1/10 oz, 1/4 oz, 1/2 oz), which makes them accessible for smaller purchases or dollar-cost averaging. GSM also produces the Lincoln Penny round and a Bitcoin-themed round in 1 oz, plus larger 2 oz and 5 oz rounds.
Because GSM rounds are privately minted (not struck by a sovereign government), they carry lower premiums than government-issued coins like the American Silver Eagle or Canadian Maple Leaf. For buyers stacking silver by weight rather than collecting specific coin programs, GSM rounds offer a good balance of recognizable design, .999 purity, and competitive pricing.

GSM produces silver bars in 1 oz, 5 oz, and 10 oz sizes. Bar premiums from GSM tend to run in line with other private mint bars -- typically lower per ounce than rounds, and lower still as bar size increases. The 10 oz GSM bar is the largest size currently tracked and usually carries the tightest premium of any GSM product on this page.

GSM offers several rounds in fractional sizes -- 1/10 oz, 1/4 oz, and 1/2 oz. Fractional silver is useful for barter-minded stackers, gifting, or building a position in smaller increments. Premiums on fractional rounds run higher per ounce than full 1 oz rounds because fabrication costs are spread over less metal, but GSM fractional pricing is competitive within the fractional silver category.
