How Much Is A Gold Bar From Costco Worth Today?

Costco is not just a place where members can buy discounted groceries and household items in bulk — they can also buy one ounce gold bars. Even better, per unprecedented increasing gold prices, those who purchased one of these gold bars — for its list price of $2,679 in September 2024 — are now sitting on a bar worth $3,549, as of September 3, 2025. The reason gold bars have increased 32.5% in value is simple: gold is hitting record levels due to demand from investors and central banks around the globe. 

However, this demand has a lot to do with uncertainty over the biggest economy in the world, the United States. As the Federal Reserve's independence is continually undermined by the Trump administration, interest rates are expected to fall. Plus, the U.S. dollar — still considered the reserve currency of the world — has dropped about 11% in value, when compared to other currencies, since President Trump took office. To add to the mix, the ongoing conflict in the Middle East and Ukraine continue to create anxiety. Some analysts, like those at JPMorgan, even predict that gold will reach $4,250 an ounce by the end of 2026. However, before rushing out to buy gold in 2025, there is a caveat to consider – its prices can swing wildly in times of uncertainty, and selling a gold bar from Costco for its full value is not as simple as it might seem.

When it comes to buying gold bars at Costco, its important to know that the sale of these bars is restricted to members, and that members are limited to one transaction per membership — with a maximum possible purchase of four units per 24 hours. The gold is also not refundable and is not eligible for price adjustments. Costco gold bars are also available in 100-gram forms for those looking to get their hands on a larger investment. As Sadiq S. Adatia, chief investment officer for BMO Global Asset Management, explained to the New York Times, Costco makes it "convenient" for consumers wanting to buy gold for the first time, "People can physically go in and pick it up and that's it, versus opening up an account and buying gold shares."

But selling is a different matter. Costco won't buy back these gold bars, and gold dealers will generally pay 5% to 10% less than market price. Plus, sellers may face potential scams, or even the experience of being severely lowballed, if they try to sell their gold online through marketplaces like eBay or Facebook Marketplace. Also, don't expect an engraving or any authentication paperwork from Costco to enhance the bar's value since most buyers will probably have to melt down the bar for resale.
