About Double Diamond Bullion

We absolutely love buying/selling vintage gold, platinum, silver, numismatic coins and definitely enjoy the history of it all.

We also produce our custom .999+ hand poured silver bars and rounds under the Experts Only/ Double Diamond Bullion brand.

It is our passion to spread the precious metals hobby as far as we can take it and enjoy it with anybody and everybody interested in participating. We have met so many great dealers and collectors along the way and are hopeful that you become a friend and a resource also.

Our goal is absolute customer satisfaction with every single person who buys from our store. We do comprehensive testing and authentication of every coin or piece of precious metal that we sell. Shipping quickly, discreetly, and packaging to protect the product is our #1 priority. If you are ever dissatisfied for any reason, we will refund your money or switch out the product until you are happy. 

We hope you enjoy the site, buy some great vintage precious metal pieces and inevitably become a friend.  That’s our goal.

Thank you for shopping here.
