About Silvano

Tangible Investments founder and president Silvano DiGenova is an authority on the rare coin market, grading, authenticity, and appraisals. In fact, since Silvano co-founded the renowned Professional Coin Grading Service (PCGS) and designed the PCGS coin grading standards, you could actually say he wrote the book on coin grading.

A budding numismatist from a young age, Silvano was also a rare coin prodigy. In 1984, during his college years, Silvano took a leave of absence from the University of Pennsylvania Wharton School to incorporate Tangible Investments of America, Inc. Through his unique ability to identify, valuate, and trade rare coins, young Silvano became a self-made millionaire at age 21. In 1986, he co-founded PCGS and was assigned the task of developing the first grading set. With its completion, Silvano had created “the standard by which certified grading was established”--the standard still used by most coin experts to this day.

In 1991, Silvano moved himself and his company from Philadelphia, Pennsylvania to Laguna Beach, California, where he opened a gallery of rare coins and fine art called Tangible Asset Galleries. Years later, he acquired Keystone Coin in Pennsylvania and also the 70-year-old Superior Galleries in Beverly Hills, and became CEO of a newly merged company known as Superior Galleries of Beverly Hills. This merger put Silvano at the head of what was then the largest rare coin auction house in California.

In 2005, Silvano sold Superior Galleries in order to make a fresh start with the Tangible Investments name. He opened a gallery in Newport Beach and in 2012 purchased new headquarters for the company in Laguna Beach, when a prime building and location became available.

Millions of collectors and investors depend on Silvano DiGenova’s expertise every day. He has been featured in Fortune Magazine’s “People to Watch,” quoted on the front page of The Wall Street Journal, interviewed in hundreds of U.S. newspapers, and has appeared several times as a commentator on CNN, FNN, CNBC, the Discovery Channel, the History Channel, and more.

Besides owning and running Laguna Beach-based Tangible Investments, Silvano is a proud member of the gallery’s surrounding community. He lives in beautiful south Laguna with his wife of thirty years and their two sons.

Curt Mease

Senior Buyer

Tangible Investments Senior Buyer Curt Mease is right where he wants to be. Born and raised in the Greater Lehigh Valley area of Bethlehem, Pennsylvania, Curt now treasures the outdoor life of southern California, traveling the U.S. for various trade shows and coin collections, and working alongside Tangible CEO and Founder Silvano DeGenova. But, his first love has always been coins and collectibles.

About Curt

Curt started collecting coins in high school, after trading his grade school stamp collection for an 1834 U.S. Half Eagle. His career with coins and collectibles began in his teens, as soon as he was old enough to drive to local antique markets and trading events and set up tables for business. Before and during college, Curt worked for a coin exchange in Allentown, Pennsylvania and for a local metallurgist, recovering and processing precious metals. After graduation, he temporarily changed professional direction, working as an annuity specialist for the Guardian Insurance & Annuity Company, an independent registered investment advisor with Mass Mutual Financial Group, and a financial consultant for PNC Bank.

But Curt’s original passion for coins and collectibles came back strong in 2005, while attending a trade show in Baltimore, Maryland. It was there Curt became reacquainted with well-known numismatist Silvano DiGenova, whom he had first met in the 1980s. The Baltimore encounter led DiGenova to offer Curt a job at Superior Galleries in Beverly Hills, where DiGenova was then CEO. With Curt’s acceptance came the move that took him from his small, home town in Pennsylvania to sunny SoCal. After DiGenova’s highly profitable sale of Superior Galleries in 2007, Curt followed DiGenova to Newport Beach to assist in opening Tangible Investments’ original gallery and to serve as its General Manager. Today, Curt relishes the narrower focus of being Senior Buyer at Tangible’s newest location in Laguna Beach.

In his free time, Curt enjoys hiking, biking, and other outdoor sports and volunteering with racing Greyhound rescue groups. He has a B.A. in financial economics from Moravian College, a post-baccalaureate degree in accounting from Muhlenberg College, and will soon complete his MBA through Phoenix University.
