While reviewing the initial results in various categories of recent auctions, my initial take is that the sales were moderate to strong.
1850 Patterns & Die Trial Values
Greysheet & Red Book® PRICE GUIDE
The Greysheet Catalog (GSID) of the Patterns & Die Trials (1849–1861) series of Private & Pioneer Gold in the U.S. Coins contains 2 distinct entries with CPG® values between $6,000.00 and $9,000.00.
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.Our Sponsors
