United States Stamp & Coin Company

What this desk does

California and the broader Pacific-mixed climate (CA) blends coastal humidity, drought ordinances, and wildfire-season risks; local providers usually know the regional regulations better than imports.

Service cues on file: numismatic expertise, bullion buying/selling, estate coin collections. That spans 3 categories. Confirm whether the same staff handle all of them or whether different specialists rotate in. Use-case alignment: Appraising rare or inherited coin collections; Buying or selling bullion and precious metals. Starting frame for the call — not a guarantee of pricing, availability, or technician skill. Where San Francisco sits within CA matters: neighborhood age, code requirements, and seasonal demand shift the dispatch calculus. Ask the dispatch line what zip codes they cover most. Treat the writeup as orientation, not vetting. The real-time dispatch conversation and written estimate carry the rest.

• Estate collections — with high confidence

How this desk compares to the alternatives

What to bring with you

1. Photo ID. Federal anti-money-laundering rules require it for any precious-metal transaction; California adds a state license check on top.
2. Pricing questions. Ask how the desk weighs the lot, verifies purity, applies fees, and records the percentage of spot or itemized numismatic value.
3. Original packaging. US Mint sets, proof boxes, certificates — they raise the offer even if the coin itself is the same piece.
4. Grading slabs. PCGS / NGC / ANACS / ICG slabs trade at known levels; bring all of them, even cracked-out cases.
5. Provenance docs. Probate paperwork, original purchase receipts, prior insurance schedules.
6. An inventory list. For mixed lots over a few hundred dollars, a written inventory keeps both sides honest.
7. A second opinion. If a single piece is potentially worth four figures, get two written offers before you sell.

Frequently asked at the counter

Will they appraise without obligation?

Most coin and bullion dealers will give a verbal appraisal for free if you might be selling — that's the standard. A written appraisal for insurance or estate purposes usually costs $50-200 or 1-2% of value because it requires more documentation.

How do I know the offer is fair?

For bullion, check the day's spot price as a reference only (kitco.com or APMEX), then ask how the shop calculates its actual bid: weight, purity, spread, premium, fees, and payment method. For numismatics, look up the coin on the PCGS Price Guide or NGC for retail comparables. If the offer is way below those marks without a clear reason, get a second opinion.

Should I clean my coins before bringing them in?

No. Cleaning a coin almost always reduces its value, sometimes by 50% or more — graders mark cleaned coins as damaged. Even a soft cloth can leave hairlines visible under magnification.

Cash, check, or wire — and is there a max payout?

Smaller transactions are usually cash or check on the spot. Anything over $10,000 in cash triggers federal IRS Form 8300 reporting. Many dealers cap same-day cash at $5,000-10,000 and pay the rest by check or wire — ask before driving over with high-value items.

What should I confirm before accepting?

Confirm store identity, dealer credentials, scale visibility, purity test, fee schedule, ID requirements, local hold-period rules, and whether the receipt lists weight, purity, and the percentage of spot applied. Directory notes do not replace a written professional valuation.

What the rules say in California

California regulates precious-metals dealers — most jurisdictions require a dealer's license, photo ID for every transaction, and a 3-15 day hold period before bought items can be resold or melted. The hold gives law enforcement time to recover stolen property; it isn't a sign of suspicion.
