Prior to his tenure in numismatics, Mike Bonham had extensive experience in the bullion markets, trading tens of millions of dollars in silver bullion on behalf of his clients. For the past 20 years, Mr. Bonham has been assisting serious collectors and astute investors in achieving their numismatic goals. He assists with lawyers, CPA financial planners, and stock brokers to help their clientele diversify their investment portfolios. He was instrumental in assembling the finest known set of proof $20 St. Gaudens gold coins and a seven-figure collection of superb quality proof Bust dimes.

Mr. Bonham aided one of his clients with the formation and liquidation of a fabulous six-figure set of Bust dollars. He executed the sale of the Sam Newhouse, III (of the Newhouse billionaire publishing family) complete Mint State $20 St. Gaudens set (less the 1927-D) - for a price approaching $1 million! Additionally, he has handled many of the finest classic U.S. rarities that have become available over the past several years, some of which are matched only by specimens in the legendary Smithsonian Collection. Following are a few examples of sets that he has either completed or was instrumental in assembling:

• The highest graded Peace Dollar set which was rated #1 by PCGS (the average grade was MS66)
• The finest known complete 1897 proof set (cent through Double Eagle)
• One of the finest complete proof Barber half-dollar collections.
• The finest known 1855 proof set (half-dime through dollar).

• Numerous other complete gold proof sets including 1890-1915.
• Several $4 Stellas sold including two PR67.

Mr. Bonham is currently involved with the management of numerous six to seven figure portfolios. He vigilantly and efficiently services the want lists of his discerning clientele. Keeping a watchful eye on their numismatic holdings, Mr. Bonham is quick to alert his clients in the event that a profit opportunity arises. As a result, he has helped numerous customers reap substantial rewards on their investment in rare coins. Mike has assisted his clients with tens of millions of dollars in acquisitions and liquidations, but is always willing to work with smaller accounts.

With a sound work ethic and unwavering dedication, he provides his clients with an extraordinary degree of personal service. In addition to advising many of our collector and investor clients, Mike also actively works with a number of wholesale dealers as well. His diligence, knowledge and commitment to customer satisfaction make him an invaluable asset to Superior Galleries.
