We specialize in San Francisco Mint gold and silver coins, and
also buy and sell all types of gold, silver and rare coins and paper money from the U.S. and around the world.
We will travel in most cases and offer fair prices for all of your collection. We won't just
pick out the gems and leave you with the rest; we will make a fair offer on all your coins
in order to make the process more convenient for you.
Shipping to us is easy. Send to PO Box 1876, Suisun City, Ca 94585. You may not need to purchase postal insurance. We have coverage with Lloyds of London written through our agent, Hugh Wood Inc. Please call us for details about acceptable methods, values and procedures. This might save you quite a bit of money as postal insurance can take a considerable bite out of the end profit you receive for your coins!
Meet us in our downtown San Francisco office or our new Fairfield office!
We strive to offer quality coins at fair prices. Our value proposition dictates that you will
find the best coins at fair prices and receive excellent customer service from our company.
That is our guarantee.
Auction: Through my attendance at major coin auctions, I can examine, evaulate, and
purchase coins on your behalf and within your budget.
Want Lists: I have access to thousands of coins through major dealers in the U.S. and
can achieve excellent pricing to help you achieve all the coins on your want list.
Consignment: I accept coins for sale on a consignment basis, and can get you top dollar
for your rarities given my contacts in the coin marketplace.
Our recent name change:
Our show organization activities are housed under the business name "Portsmouth Square Coin & Bourse Company, LLC". Our everyday coin activities are still done under the entity called "Griffin Coins". There are several reasons for this change. I won't bore you with the details!
