Why San Francisco, CA Is a Premier Destination for Coin Appraisals
The Bay Area’s numismatic reputation wasn’t built overnight. When we work with collectors throughout neighborhoods like Russian Hill, the Marina District, and down to Silicon Valley communities in Mountain View and Palo Alto, we’re drawing on a legacy that began with the California Gold Rush and the establishment of the San Francisco Mint over 170 years ago.
Seven Decades of Established Expertise
San Francisco’s oldest coin dealers have served the community since the 1950s. Robert R. Johnson Coin and Stamp Company, established in 1954, has been operating continuously for over 70 years. Witter Coin has provided coin appraisals in San Francisco since 1960, positioning itself as the region’s “#1 buyer of old coins.” When our teams evaluate collections in the Financial District or near the Embarcadero, we often encounter coins that have passed through these same firms multiple times over generations.
This longevity matters because rare coin appraisal requires institutional knowledge. Understanding the subtle differences between an 1879-S Morgan dollar in MS-64 versus MS-65 condition—a distinction worth potentially thousands of dollars—comes from decades of hands-on experience examining tens of thousands of specimens.
The Gold Rush Legacy and Local Coin Culture
San Francisco’s relationship with precious metals runs deep. The city’s historic role as the financial center of the Gold Rush created a unique concentration of rare Western coinage. When appraising rare coins in the San Francisco Bay Area, dealers frequently encounter $20 Liberty Double Eagles, $10 Indians, and territorial gold pieces minted right here in California between 1854 and the early 1900s.
The region’s wealth concentration—from Pacific Heights mansions to Silicon Valley estates—has created consistent demand for professional numismatic services. Bay Area appraisers routinely handle collections valued from a few hundred dollars to well over $1,000,000, requiring sophisticated expertise and secure facilities.
International Port City Advantage
San Francisco’s status as an international gateway means local dealers have developed deep expertise in foreign coins and world currency. Our appraisers in the Bay Area regularly evaluate Chinese gold pandas, British sovereigns, Mexican pesos, and currency from across Asia and Europe—material that collectors in other U.S. markets rarely encounter.
How Professional Coin Appraisal Works in the Bay Area
Understanding the appraisal process helps you prepare properly and recognize quality service. When we evaluate collections—whether in our showroom near Union Square or at a client’s home in Sausaloga or Los Gatos—we follow industry-standard protocols that align with national grading organizations.
Authentication and Grading Standards
Professional Bay Area appraisers are typically members of the American Numismatic Association (ANA) and serve as authorized submitters to the three major third-party grading services: PCGS (Professional Coin Grading Service), NGC (Numismatic Guaranty Company), and CAC (Certified Acceptance Corporation).
During an appraisal, coins are examined for:
- Authenticity: Verification that the coin is genuine, not counterfeit or altered
- Grade: Assessment on the 1-70 Sheldon scale, considering wear, luster, strike quality, and eye appeal
- Rarity factors: Date, mintmark, variety, and population census data
- Originality: Detection of cleaning, re-toning, or other alterations that diminish value
- Market demand: Current collector interest and recent auction results for comparable pieces
Numismatic Value vs. Precious Metal Content
One critical distinction Bay Area appraisers make is between numismatic (collector) value and intrinsic metal value. With gold at $4,326.15 per ounce and silver at $65.38 per ounce as of December 20, 2025, even common-date gold coins carry significant base value.
A common-date $20 Saint-Gaudens gold piece contains 0.9675 troy ounces of gold, giving it a melt value of approximately $4,186. However, in uncirculated condition, the same coin might have a numismatic value of $5,000-$7,000 or more, depending on grade and eye appeal. Professional appraisers calculate both values and recommend whether coins should be sold as bullion or collectibles.
Types of Appraisal Services Available
Bay Area dealers offer multiple service levels to match different needs:
| Service Type | Best For | Typical Cost |
|---|---|---|
| Walk-in Verbal Appraisal | Small collections, quick evaluations, immediate sale consideration | Usually free |
| Formal Written Appraisal | Insurance documentation, estate planning, tax purposes | $100-$500+ depending on collection size |
| In-Home Estate Appraisal | Large collections, probate situations, clients unable to travel | Often free if selling; fee-based for documentation only |
| Pre-Auction Appraisal | Rare or high-value pieces destined for auction consignment | Typically free when consigning |
Common Mistakes When Seeking Coin Appraisals
We’ve seen collectors make costly errors when working with San Francisco coin dealers. Avoiding these pitfalls can mean thousands of dollars in recovered value.
Cleaning Coins Before Appraisal
The single most destructive thing a coin owner can do is clean their coins. What looks like helpful polishing to an untrained eye can reduce a coin’s value by 50-90%. Professional grading services will mark cleaned coins as “Details” grades, which carry substantial discounts compared to problem-free examples.
Original toning—even if it looks dark or unattractive to you—is often desirable to collectors. When our teams appraise collections in Nob Hill or the Mission District, we frequently encounter coins that were “improved” by well-meaning owners, turning $500 coins into $50 pieces.
Accepting the First Offer Without Comparison
Bay Area dealers operate with varying business models. Some specialize in quick bullion transactions and offer 60-70% of retail value. Others focus on numismatic coins and may pay 75-90% for premium pieces they can resell to collectors. Getting multiple appraisals—especially for coin buyers who provide written appraisals—ensures you understand the true market range.
Relying Solely on Online Price Guides
Online guides provide rough estimates but cannot account for the subtle factors that dramatically affect value. A 1921 Morgan dollar might be listed at $30 in a guide, but if it happens to be the scarcer VAM variety in high grade, it could be worth $300 or more. Professional Bay Area appraisers have the specialized references and experience to catch these distinctions.
Choosing the Right Appraiser in San Francisco, CA
Not all appraisers offer the same level of expertise or transparency. Here’s what to look for when appraising rare coins in the San Francisco Bay Area.
Professional Credentials and Memberships
Reputable appraisers should be members of the American Numismatic Association and authorized submitters to PCGS, NGC, or both. These affiliations demonstrate that the firm meets professional standards and has passed background checks required by grading services.
Transparent Education During Appraisal
The best Bay Area appraisers take time to educate clients about grading factors, rarity, and market conditions. If an appraiser simply makes a blanket offer without explaining how they arrived at their valuation, consider it a red flag. Quality firms will show you comparable auction results, grading population reports, and explain condition issues.
Established Local Presence
Firms with decades of operation in San Francisco have reputations to protect. Businesses established in the 1950s-1960s didn’t survive 60-70 years by underpaying clients or providing poor service. While newer dealers can certainly be reputable, longevity provides additional assurance.
What to Expect During Your Appraisal Appointment
Understanding the typical appraisal process helps you prepare and ensures you get maximum value from the consultation.
Initial Sorting and Organization
The appraiser will first sort your coins by type, denomination, and era. This organizational step helps identify which pieces warrant detailed individual examination versus those that can be evaluated as groups (common-date circulated coins, for example).
Detailed Examination of Key Pieces
Using magnification and proper lighting, the appraiser will examine significant pieces individually. They’ll check for mint errors, varieties, and condition issues. This is when you’ll learn whether your coin is MS-63 or MS-65—differences that can mean thousands of dollars on rare dates.
Valuation and Documentation
For verbal appraisals, you’ll receive immediate feedback on value ranges. For formal written appraisals, the dealer will prepare a detailed report listing each significant coin with its description, grade, and appraised value. These documents are suitable for insurance policies, estate filings, or IRS documentation.
Frequently Asked Questions About Bay Area Coin Appraisals
How much does a professional coin appraisal cost in San Francisco?
Most Bay Area dealers offer free verbal appraisals if you’re considering selling. Formal written appraisals for insurance or estate purposes typically cost $100-$500 depending on collection size, though some firms waive fees for larger estates. Always clarify costs upfront.
Should I get my coins professionally graded before appraisal?
Not necessarily. Professional grading by PCGS or NGC costs $20-$100+ per coin. Your appraiser can advise which coins (if any) would benefit from third-party certification. Generally, only coins worth $500+ in today’s market justify grading costs, and your appraiser can identify those candidates.

A small collection of 20-50 coins might take 30-60 minutes. Larger estates with hundreds or thousands of pieces may require several hours or multiple appointments. Quality appraisers won’t rush—proper evaluation takes time.
Do I need an appointment, or can I walk in?
Many San Francisco dealers accept walk-ins for small collections, but appointments are recommended for larger holdings or if you need dedicated time with a senior numismatist. Call ahead, especially if you’re traveling from Oakland, CA or other East Bay locations.
What should I bring to my appraisal appointment?
Bring your coins in their current holders—don’t remove them from albums or cases. If you have any documentation (previous appraisals, purchase receipts, inheritance paperwork), bring that as well. For estate appraisals, power of attorney or executor documentation may be required.
