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! 

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.
