Costco Gold, Silver & Platinum: Complete Guide to Availability, Pricing, and Purchase Limits

Costco’s entry into the bullion market has been one of the biggest stories in precious metals over the past two years. What started with 1 oz gold bars in 2023 has expanded into a full precious metals program covering gold coins, gold bars, silver coins, silver bars, silver rounds, and platinum bars — generating hundreds of millions of dollars in monthly bullion sales according to Costco’s own financial disclosures.

For bullion buyers, the key questions are always the same: what’s currently available, what are the purchase limits, and is the price actually competitive? This guide covers all of it, with current information as of April 2026.

What Precious Metals Does Costco Sell?

Costco’s bullion program has grown significantly since its launch. Here’s the complete current product lineup:

Silver Bars

10 oz Silver Bar — PAMP Lady of Liberty — 99.9% fine silver, proof-like finish. Limit: 1 transaction per membership, max 10 units per day.
10 oz Silver Bar — PAMP Lady of Justice — 99.9% fine silver, newer addition to the lineup.

Silver Rounds

Platinum

1 oz Platinum Bar — PAMP Suisse Fortuna — 99.95% fine platinum in sealed assay packaging.

Note: Product availability on Costco.com changes frequently. Items sell out and are restocked on an irregular schedule. Costco does not sell precious metals in Louisiana, Nevada, or Puerto Rico.

Purchase Limits and Restrictions

Costco has tightened purchase limits as demand has surged, particularly during periods of rapid price movement. Current limits as of April 2026:

Gold: 1 transaction per membership, maximum 4 units per 24 hours for coins and bars.

Silver coins: 1 transaction per membership, maximum 10 units per day. For a 20-count Silver Eagle tube, that means up to 200 coins (200 oz) per day. For 25-count Maple Leaf tubes, up to 250 coins per day.

Silver bars and rounds: 1 transaction per membership, maximum 10 units per day.

Platinum: Same structure — 1 transaction per membership per day.

These limits were restructured in early 2026 in response to rapid silver price appreciation that outpaced Costco’s ability to reprice inventory in real time. The limits cap individual transaction sizes while still allowing multiple daily transactions, which helps Costco manage margin risk during volatile price swings.

All precious metals purchases require an active Costco membership (Gold Star or Executive) and must be made online at Costco.com. Precious metals are not available in-store at warehouses. Standard shipping via FedEx insured is included in the price, with delivery typically in 3–5 business days.

Is Costco’s Pricing Competitive?

This is the question every bullion buyer asks — and the answer depends on what you’re buying and how you’re paying.

The Costco advantage: Costco members who pay with a Costco Visa card earn 2% cash back (Executive members) on top of the 2% Executive membership reward, potentially stacking to 4% back on bullion purchases. That effectively reduces the premium by 2–4%, which can make Costco’s per-ounce cost competitive with or better than online bullion dealers — especially on gold, where the absolute dollar amount of the cashback is significant.

The Costco limitation: Costco’s product selection is narrow compared to dedicated bullion dealers. You can’t buy individual Silver Eagles, fractional gold coins (1/4 oz, 1/10 oz), specific date coins, certified/graded coins, junk silver, or monster boxes from Costco. For those products, online bullion dealers are your only option.

How to compare: The best way to evaluate Costco’s pricing is to check the per-ounce cost (including any credit card rewards) against the same product from online dealers. FindBullionPrices tracks real-time pricing across 15+ dealers:

Compare Silver Eagle Prices — see how Costco’s tube pricing compares to online dealers
Compare Silver Bar Prices — compare 10 oz bar premiums
Compare Gold Coin Prices — 1 oz Gold Eagle and Gold Buffalo pricing from multiple dealers
Compare Gold Bar Prices — 1 oz gold bar pricing including PAMP and Rand Refinery
Best Silver Prices — the broadest silver comparison across all product types

In general, Costco’s listed prices (before credit card rewards) are competitive but not always the lowest. Online bullion dealers that offer ACH/wire payment discounts of 2–4% can match or beat Costco’s pricing on the same products — especially for buyers who don’t have an Executive membership or Costco Visa.

Costco’s Silver Supply Chain

Costco doesn’t publicly disclose its bullion fulfillment partner, but the products and packaging are consistent with supply from one of the U.S. Mint’s Authorized Purchaser network. The PAMP silver bars and rounds suggest a direct or indirect relationship with MKS PAMP Group.

Some customers have reported packaging issues with silver coin tubes — broken seals, coins loose in shipping boxes, or minor contact marks from transit. This is a known concern with the Costco fulfillment process, which uses standard commercial shipping rather than the specialized bullion packaging that dedicated precious metals dealers typically employ. For coins you plan to have graded, this matters; for bullion-value stacking, it generally doesn’t.

Costco’s return policy for precious metals is notably restrictive: bullion purchases are non-refundable. This is a significant difference from the standard Costco return policy that most members are accustomed to.

What Costco Doesn’t Sell

Knowing what Costco doesn’t offer is just as useful as knowing what they do. For these products, you’ll need an online bullion dealer:

Individual silver coins (1 oz) — Costco only sells tubes of 20 or 25
Fractional gold coins — no 1/2 oz, 1/4 oz, or 1/10 oz options
Monster boxes (500 coins) — not available at Costco
Junk silver / constitutional silver — pre-1965 90% silver coins
Certified/graded coins (NGC MS-70, PCGS MS-70) — no graded products
Proof coins — no proof Silver Eagles or Gold Eagles
Specific date/year coins — you get whatever the current year is
Silver rounds in 1 oz format — Costco’s rounds are 10 oz only
Kilo or 100 oz silver bars — Costco’s bars are 10 oz only
Palladium — not currently offered

Should You Buy Bullion from Costco?

Costco makes sense for buyers who:

Already have an Executive membership and Costco Visa (maximizing the 2–4% rewards stack)
Want the convenience of buying from a retailer they already trust
Are buying gold bars or gold coins where the per-ounce cashback is substantial (4% on a $5,000 gold coin = $200 back)
Don’t need specific products, dates, or formats beyond what Costco offers

Online bullion dealers make more sense for buyers who:

Want the lowest possible premium with ACH/wire payment (2–4% discount)
Need specific products: fractional gold, junk silver, monster boxes, proofs, certified coins
Want to compare across 15+ dealers rather than accepting a single price
Prefer specialized bullion packaging and handling
Plan to have coins graded (Costco’s shipping can cause contact marks)

The smartest approach for many buyers is to use both: Costco for gold bars and gold coins where the credit card rewards math works in your favor, and online dealers (tracked on FindBullionPrices) for silver products and specialty items where product selection and premium comparison drive better value.

Frequently Asked Questions

Does Costco sell silver coins?

How much do Costco silver coins cost?

Use our Silver Eagle price comparison tool to see real-time pricing across multiple dealers.

Is there a limit on how much silver you can buy at Costco?

Yes. As of April 2026, silver coin purchases are limited to 1 transaction per membership with a maximum of 10 units per day. For Silver Eagle 20-count tubes, that means up to 200 coins per transaction. Purchase limits have been tightened during periods of high demand and rapid price movement.

Can you return bullion to Costco?

No. Precious metals purchases are non-refundable. This is an exception to Costco’s standard return policy.

Is Costco cheaper than online bullion dealers?

It depends on the product and how you pay. Costco Executive members using a Costco Visa can earn up to 4% back, which effectively lowers the per-ounce cost. However, online bullion dealers that offer 2–4% ACH/wire discounts can match or beat Costco pricing, especially on silver products. The best approach is to compare: use FindBullionPrices to check current dealer pricing against Costco’s listed price.
