The Greysheet Catalog (GSID) of the Dubosq & Company (1850) series of Private & Pioneer Gold in the U.S. Coins contains 2 distinct entries with CPG® values between $30,000.00 and $660,000.00.

Collectors consider this piece the first of the California private gold coins. A newspaper account dated May 31, 1849, described a five-dollar gold coin, struck at Benicia City, though with the imprint San Francisco. It mentioned the private stamp of Norris, Gregg & Norris. The initials N.G.&N. were not interpreted until 1902, when the coins of Augustus Humbert were sold.
