Our staff has over 200 years combined experience in the collectibles market and has transacted over $2 billion in the last 30 years! Thanks to our expertise, you can rest assured your item will be identified properly so you receive its true value.

We would appreciate the opportunity to provide you with a free verbal appraisal of your items. We can then assist you with keeping your values update, helping you liquidate when the time is right or continue to add to your collections at great prices.


Tangible Investments, Inc. is owned and operated by world-renowned coin expert Silvano DiGenova, who has been in the coin buying and selling business for more than 30 years. Silvano DiGenova is not only a co-founder of the Professional Coin Grading Service (PCGS)–the largest, most prestigious service for evaluating and grading coins—but singlehandedly designed the standard that is used by PCGS and the entire rare coin industry.

As the leading coin dealership in southern California and one of the nation’s most respected firms, we guarantee to give you the “real deal” on your tangible items.


Our company founder and president, Silvano DiGenova, has literally traded hundreds of millions of dollars via auctions. As the former CEO of Superior Galleries of Beverly Hills, Mr. DiGenova led a team of professionals at the oldest and largest rare coin auction house in California. In 2005, the State of California entrusted him with a two-year contract to be the official auctioneer for unclaimed property.

Our highly-qualified team consists of awarding winning catalogers and rare coin specialists, and they experience and training at several world-famous auction houses, such as Sotheby’s, Bowers and Merena, and Heritage Auctions.

In addition, Tangible Investments buys and sells at all major auction houses throughout the United States, Europe, and Asia. We have a constant presence at auction firms such as Bonhams, Sotheby’s, Christie’s, IM Chait, Heritage, Stack’s Bowers, and many others. Due to the sheer volume of our auction business, we are afforded special rates and incentives rarely offered to individuals.

Whether buying or selling, it is in your financial best interest to speak with us first. We will select the proper venue for you, and provide you with a settlement package far better than you would receive by dealing directly with any major auction house.


If you have ever bought or sold collectibles at auction, then you are aware of the fact that auction houses charge from 5% to 20% on both sides of the transaction. Because Tangible Investments transacts tens of millions of dollars per year with all of the major auction firms, we receive special rates not available to most individual buyers and sellers.

Usually, your best bet is to sell to us outright. However, there are times when a significant auction is the best venue for exceptional rarities. By consigning your valuables to Tangible Investments and allowing us to serve as your representative, you will net more at settlement time than by dealing directly with a major auction house. Not only will we guide you to the best venue, we will also share in our discounts so that you maximize the return on your valuables when it is time to sell.
