Payment Processing for Precious Metals Dealers in San Francisco

Precious metals dealers payment processing in San Francisco is a narrower problem than most merchant services articles admit. The city has a real cluster of coin shops, bullion dealers and estate buyers, from the older storefronts around the Financial District and Union Square to appointment-only offices in SoMa and dealers who work the Bay Area coin shows. Every one of them has run into the same wall: card processors either decline the category outright or approve it and then freeze funds after the first large gold order. Understanding why is the first step to building an acceptance stack that works.

Why bullion is a high-risk category

Three reasons, and they compound. First, gold and silver are close to cash. A criminal with a stolen card who buys an ounce of gold has converted the card into a liquid asset with no serial number attached. Second, the price moves. If a customer locks a price on Monday, spot falls by Thursday, and the buyer disputes the charge, the dealer has sold a product that is now worth less than the refund. Third, the ticket sizes are large and lumpy, which makes a dealer's monthly volume look erratic to an underwriter.

Card networks assign bullion and coin dealers to MCCs that most acquirers restrict. That does not mean approval is impossible. It means the file goes to a processor that underwrites the category on purpose, with reserves and volume limits at the start.

The price-lock chargeback problem

The dispute that hurts dealers most is not fraud; it is buyer's remorse dressed up as a chargeback. Spot drops, the customer claims the product was not as described or was never received, and the dealer is fighting a dispute while holding a market loss. Defenses that work:

• A written market-loss policy accepted at checkout, stating the customer owes the difference on cancelled locked orders.
• Signature-required shipping with insurance and tracking on every order.
• Invoices that show the locked spot price, premium, and timestamp.
• Card acceptance only for orders under a stated threshold, with wire or ACH above it.

Keep total disputes well under the roughly 1% ratio that triggers Visa and Mastercard monitoring. A dealer with a few dozen card transactions a month can hit that ratio with a single dispute, which is another argument for keeping card volume small and clean.

Structuring the acceptance stack

Established dealers in the city tend to run three rails:

1. Cards for numismatic coins, supplies, small bullion orders and walk-in retail, often with a card premium. Under SB 478, any mandatory fee must be included in the advertised price, and the state surcharge rules limit how a card surcharge can be presented, so confirm the current rule with your processor and counsel before posting separate cash and card prices.
2. ACH debits for repeat customers and mid-size orders, settling in 1-3 business days. Dealers typically ship after the return window for the common codes has passed.
3. Wire for large orders, with product shipped only on confirmed receipt.

Some dealers add stablecoin payments for customers who hold digital dollars and want instant settlement to the merchant wallet without a wire cutoff. If you accept digital assets, review whether California's Digital Financial Assets Law affects your activity and confirm with counsel.

Compliance that underwriters will ask about

Dealers in precious metals, stones and jewels are covered by federal anti-money-laundering rules above certain purchase and sale thresholds, which means a written AML program, customer identification and record retention. California also has its own secondhand dealer and pawn rules that touch estate buying. A processor will ask for your AML program, your refund and market-loss policy, and your shipping procedures. Having them ready shortens underwriting from weeks to days. For cardholder data specifically, using hosted fields keeps card numbers out of your website and reduces your PCI scope.

Fraud controls that fit the product

Address verification alone does not stop bullion fraud, because fraudsters often have the billing address. What helps: velocity limits on new customers, matching ship-to and bill-to on first orders, holding first-time card orders for manual review, and declining orders shipped to freight forwarders or mail drops. Layer a fraud detection tool on top so rules run automatically instead of relying on whoever is at the counter.

What approval looks like

Expect a rolling reserve, a monthly volume cap, and a per-transaction ceiling on cards at the start. Expect the processor to review after a few months of clean processing. Do not expect to run a $40,000 platinum order on a card on day one, and be suspicious of anyone who says you can.

San Francisco dealers who survive long-term treat card acceptance as a convenience for small orders and put the real volume on rails built for it. Set up the stack that way and the processing relationship stops being the most fragile part of the business.
