Three years after listing its first two gold bars, Costco has built a precious metals catalog spanning 56 gold products, multiple silver coin and bar options, and platinum. What started as a 1 oz PAMP Suisse Lady Fortuna and a Rand Refinery bar in the summer of 2023 now includes gold coins, themed gold bars, silver coin tubes from three sovereign mints, the retailer’s own Kirkland Signature silver bars, cast bars up to 100 ounces, and a PAMP platinum bar.
The questions for bullion buyers remain the same: what is available right now, what are the purchase limits, and is the price competitive with online bullion dealers? This guide covers the full Costco precious metals catalog with current information as of September 2026.
The Complete Costco Precious Metals Catalog
Costco’s bullion program has expanded significantly since launch. The catalog now covers gold, silver, and platinum from five refiners and three sovereign mints. Here is the current product lineup.
Gold Coins
- 2026 1 oz American Gold Eagle (91.67% fine gold, 22K). Produced by the U.S. Mint. Limit: 1 transaction per membership, max 2 units per 24 hours.
- 2026 1 oz American Gold Buffalo (99.99% fine gold, 24K). Produced by the U.S. Mint. Same purchase limits as the Gold Eagle.
- 2026 1 oz Canadian Gold Maple Leaf (99.99% fine gold). Produced by the Royal Canadian Mint. Availability is less predictable than bars.
Gold Bars
The gold bar catalog has grown to 56 SKUs across multiple refiners, weights, and themed designs. Core offerings include:
- 1 oz Gold Bar, Rand Refinery (99.99% fine gold). One of Costco’s original bullion products.
- 1 oz Gold Bar, PAMP Suisse Lady Fortuna (99.99% fine gold). Sealed assay card with Veriscan technology.
- 1 oz Gold Kinebar, Argor-Heraeus (99.99% fine gold). Holographic security feature on the reverse.
- 1 oz Gold Bar, Argor-Heraeus Origin Traced (99.99% fine gold). Documented provenance from mine to market.
- 1 oz Gold Bar, PAMP Good Luck Dragon (99.99% fine gold). One of several themed PAMP designs.
- 1 oz Gold Bar, PAMP Lunar Legends Azure Dragon (99.99% fine gold). Themed collector bar in assay card.
- 10 gram Gold Bar, Argor-Heraeus Small Craft (99.99% fine gold). Smallest gold product in the lineup.
- 25 gram PAMP Good Luck Dragon Multigram Bar (99.99% fine gold). Divisible bar with individual 1-gram segments for gifting or fractional gold stacking.
- 10 oz Gold Bar, PAMP Suisse Lady Fortuna (99.99% fine gold). The largest and most expensive gold product Costco offers.
Most gold listings are not in stock at any given time. Tracker sites report that roughly 11 of 56 gold SKUs are available on a typical day, with restocks happening 3 to 5 times per week, concentrated on Thursday and Friday mornings between 5:00 and 8:00 AM ET. Products typically sell out in 1 to 4 hours. For current gold bar bullion prices across online dealers, see the comparison page. For gold coin comparisons, see the gold coins page.
Silver Coins
- 2026 1 oz American Silver Eagle, 20-count tube (99.9% fine silver). Produced by the U.S. Mint. Limit: 1 transaction per membership, max 10 units per day.
- 2026 1 oz Canadian Silver Maple Leaf, 25-count tube (99.99% fine silver). Produced by the Royal Canadian Mint. Includes Bullion DNA anti-counterfeiting technology.
- 2026 1 oz British Silver Britannia, 25-count tube (99.9% fine silver). Produced by The Royal Mint. A newer addition to the silver coin lineup.
Adding the Britannia gives Costco silver coins from three of the world’s major sovereign mints. Compare current Silver Eagle bullion prices across tracked dealers to see how Costco’s tube pricing compares.
Silver Bars
- 1 oz Kirkland Signature Silver Bar, 5-pack (99.99% fine silver). Costco’s own branded silver product with a proof-like finish, individually packaged in Kirkland Signature assay cards. Limit: 1 transaction per membership, max 5 units per 24 hours.
- 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).
- 10 oz Silver Bar, PAMP Good Luck Dragon (99.9% fine silver).
- 1 oz Silver Bar, PAMP Lady of Justice, 20-count pack (99.9% fine silver).
- 100 oz Silver Cast Bar, PAMP (99.9% fine silver). Limit: 1 transaction per membership, max 1 unit per 24 hours.
- 100 oz Silver Cast Bar, ABC Refinery (99.9% fine silver). Same limits as the PAMP 100 oz bar.
The Kirkland Signature bars are notable as the first precious metal product sold under Costco’s private label. At roughly $370 for a 5-pack with silver spot near $64, the premium runs about 7% over spot, which is in line with typical 1 oz silver bar premiums from online bullion dealers. The 100 oz bars represent a serious capital commitment at current silver prices (roughly $6,400 at spot) and are the kind of product that historically appeared only at dedicated bullion dealers.

Silver Rounds
- 10 oz Silver Round, Sunshine Minting 250th Anniversary American Eagle (99.9% fine silver). A commemorative product tied to the 2026 U.S. Semiquincentennial.
Platinum
- 1 oz Platinum Bar, PAMP Suisse Fortuna (99.95% fine platinum). Sealed assay packaging. Added to the program in October 2024. Premiums run higher than gold (roughly 8% over spot versus 1% to 2% for gold bars). The selection has not expanded beyond this single product.
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 multiple times as demand has surged, most recently in response to rapid silver price appreciation in early 2026 that outpaced the retailer’s ability to reprice inventory in real time. Current limits as of September 2026:
| Product Category | Per-Transaction Limit | Per-24-Hour Limit |
|---|---|---|
| Gold coins and bars | 1 transaction per membership | 2 units |
| Silver coin tubes | 1 transaction per membership | 10 units |
| Silver bars (10 oz) | 1 transaction per membership | 10 units |
| Kirkland Signature silver bars (5-pack) | 1 transaction per membership | 5 units |
| Silver bars (100 oz) | 1 transaction per membership | 1 unit |
| Platinum | 1 transaction per membership | Per product listing |
Addresses receiving more than eight units of any precious metal product per day may see orders canceled. All purchases require an active Costco membership (Gold Star at $65/year or Executive at $130/year) and must be made online at Costco.com. Precious metals are not available in warehouses. Standard insured shipping via FedEx is included in the price, with delivery typically in 3 to 5 business days.
Costco’s return policy for precious metals is notably restrictive: bullion purchases are non-refundable. This is a significant departure from the retailer’s standard return policy. Costco does not offer a buyback program. If you want to sell, you will need to go through a dealer, local coin shop, or secondary market.
Is Costco’s Pricing Competitive?
The answer depends on what you are buying and how you are paying.
The Costco advantage. Members who pay with a Costco Visa card earn 2% cash back. Executive members add a 2% annual membership reward on top of that, potentially stacking to 4% back on bullion purchases. On a gold bar listed at $4,400, a 4% return puts $176 back in your pocket. If Costco’s markup is 2% over spot, the 4% reward more than covers the premium and pushes your effective cost below spot. For the full breakdown, see our Costco rewards stacking guide.
The Costco limitation. Product selection is narrow compared to dedicated bullion dealers. You cannot buy individual Silver Eagles, fractional gold coins, specific date coins, certified or 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:
- Silver Eagle bullion prices: see how Costco’s tube pricing compares
- Closest-to-spot silver: the lowest silver bullion premiums available today
- Closest-to-spot gold: the lowest gold bullion premiums available today
- 1 oz gold bar bullion prices: PAMP, Rand Refinery, and Argor-Heraeus pricing
- Best silver bullion 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 or wire payment discounts of 2% to 4% can match or beat Costco’s pricing on the same products, especially for buyers who do not have an Executive membership or Costco Visa.
Supply Chain and Packaging
Costco does not publicly disclose its bullion fulfillment partner, but the products and packaging are consistent with supply from the U.S. Mint’s Authorized Purchaser network. The PAMP bars and rounds suggest a direct or indirect relationship with MKS PAMP Group. The Kirkland Signature silver bars are struck to .9999 fineness with a proof-like finish, suggesting a contracted refiner producing to Costco’s specifications.
Some customers have reported packaging issues with silver coin tubes: broken seals, coins loose in shipping boxes, or minor contact marks from transit. Costco 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 does not.
What Costco Does Not Sell
Knowing what Costco does not offer is just as useful as knowing what they do. For these products, you 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 or graded coins (NGC, PCGS): no graded products
- Proof coins: no proof Silver Eagles or Gold Eagles
- Specific date or year coins: you get whatever the current year is
- 1 oz silver rounds: Costco’s only round is 10 oz
- Kilo silver bars: available in 1 oz, 10 oz, and 100 oz only
- Palladium: not offered
Costco vs. Online Bullion Dealers: Who Should Buy Where
Costco makes sense for buyers who already have an Executive membership and Costco Visa (maximizing the 2% to 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, and do not 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 or wire payment, need specific products (fractional gold, junk silver, monster boxes, proofs, certified coins), want to compare bullion prices across multiple dealers rather than accepting a single listed price, prefer specialized bullion packaging and handling, or plan to have coins graded.
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?
Yes. Costco currently sells 2026 American Silver Eagle coins in 20-count tubes, 2026 Canadian Silver Maple Leaf coins in 25-count tubes, and 2026 British Silver Britannia coins in 25-count tubes. They also sell Kirkland Signature 1 oz silver bars in 5-packs, 10 oz PAMP silver bars, 100 oz cast silver bars, and 10 oz Sunshine Minting silver rounds. All purchases require a Costco membership and must be made online at Costco.com.
How much do Costco silver coins cost?
Costco’s silver pricing changes throughout the day based on the spot price. The per-coin cost in a Costco Silver Eagle tube is generally competitive with online bullion dealers, though dedicated dealers offering ACH payment discounts may match or beat it. Use the Silver Eagle bullion 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. Silver coin tube 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 (200 oz) per transaction. Kirkland Signature silver bar 5-packs are limited to 5 units per 24 hours, and 100 oz cast bars are limited to 1 per day. Purchase limits have been tightened multiple times during periods of high demand.
Does Costco sell gold bars?
Yes. Costco’s gold catalog has grown to 56 SKUs, including 1 oz gold bars from Rand Refinery, PAMP Suisse, and Argor-Heraeus, as well as 1 oz Gold Eagle, Gold Buffalo, and Gold Maple Leaf coins. Gold purchases are limited to 1 transaction per membership, max 2 units per 24 hours.
What are the Kirkland Signature silver bars?
The Kirkland Signature silver bars are Costco’s private-label 1 oz silver bars struck to .9999 fineness with a proof-like finish. They are sold in 5-packs with each bar individually sealed in a Kirkland Signature branded assay card. They are the first precious metal product to carry Costco’s in-house brand.
Does Costco sell platinum?
Yes. Costco sells 1 oz PAMP Suisse Fortuna platinum bars in sealed assay packaging. Platinum was added to the program in October 2024. The selection has not expanded beyond this single product.
Can you return bullion to Costco?
No. Precious metals purchases are non-refundable and not eligible for price adjustments. 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% to 4% ACH or wire discounts can match or beat Costco pricing, especially on silver products. The best approach is to compare: use FindBullionPrices to check current dealer bullion pricing against Costco’s listed price.
