Gold is near an all-time high—here's how much a Costco bar bought a year ago is worth today

Costco's gold bar sales have surged, driven by a nearly 45% increase in spot gold prices year-over-year, leading the retailer to restrict purchases to two bars per day. A gold bar purchased from Costco for $2,399.99 in June 2024 would be worth approximately $3,390 as of Tuesday, June 17th, 2025, representing an unrealized gain of $990, or 41.3%. While selling gold can be profitable, sellers should expect to receive 5% to 10% less than the spot price and be aware that profits are taxed as collectibles at a federal long-term capital gains rate of up to 28%.

Analysis

Costco has experienced a surge in demand for its gold bars, first offered in 2023, driven significantly by a sharp rise in spot gold prices, which were reported to be around $3,390 per ounce as of a recent Tuesday, approximately 45% higher year-over-year and near record highs. This increased appeal led Costco to tighten purchase restrictions in May, limiting members to one transaction of up to two bars per day. Illustratively, a 1-ounce gold bar purchased from Costco in June 2024 for $2,399.99 could represent an unrealized gain of $990, or 41.3%, by June 17, 2025, based on a spot price of $3,390. The heightened interest in gold aligns with historical investor behavior during periods of geopolitical instability, inflation, and U.S. dollar strength concerns. However, realizing profits from these gold bars involves practical considerations: sellers typically receive 5% to 10% less than the spot price, with brick-and-mortar bullion dealers potentially offering more favorable rates (1% to 5% below spot) compared to pawn shops or online marketplaces like eBay and Facebook Marketplace, which are advised against due to risk. Furthermore, any profits are subject to potentially higher taxation, as the IRS classifies physical gold as a collectible, meaning federal long-term capital gains can be taxed at up to 28%, exceeding the maximum 20% rate for stocks or real estate, and short-term gains are taxed as ordinary income.

Key Decisions for Investors

• Investors in Costco (COST) should view the strong demand for its gold bars, reflected by a +0.7 sentiment score, as a positive indicator of the retailer's ability to attract customers with unique offerings, although the direct financial impact may be limited.
• Prospective gold investors attracted by the recent 45% year-over-year price increase should meticulously calculate net potential returns, accounting for typical selling discounts of 5-10% below spot price and the higher federal capital gains tax rate of up to 28% for collectibles.
• Individuals looking to sell gold acquired from Costco or other sources are advised to seek out reputable bullion dealers, who may offer prices 1-5% below spot, and to avoid private sales or platforms like eBay and Facebook Marketplace, which carry higher risks and potentially less favorable terms, as reflected by their negative sentiment scores.
• Given the 'cautious' overall market tone despite gold's price surge, existing gold holders should reassess their positions, considering the total cost of realization including transaction fees and taxes, before making decisions to take profits.
