Probably issued ca. 1915. Length 118 mm, bowl diameter 44 mm. 329.0 grains. Excellent condition. Floral pattern handle is topped by the standing figure of a California Gold Rush miner with pick and raised hand, STERLING is impressed at the back of the stem. The bowl bears a precise impression of an 1852 United States Assay Office of Gold $50 obverse style die bearing Charles Cushing Wright's eagle and shield, scroll inscribed 900 THOUs and the name KUNER F. This identifies Bavarian-born Georg Albrecht Ferdinand (Albert) Kuner, who prepared the dies for a number of well-known Pioneer Gold issues. His name appeared only on the later British Columbia issues of 1862. According to Donald H. Kagin, dies for the USAOG $50 "Slugs" survived until the great San Francisco earthquake and fire of 1906. One obverse was salvaged from the ruins and used to produce a very limited number of spoons at the time of the Panama-Pacific International Exposition of 1915. Identical in style to the example offered in our (Stack's) Americana Sale of January 2009, lot 8808, (which sold for $4,025) but with somewhat smaller length, width and weight. It seems likely that these spoons were offered for sale as souvenirs at the 1915 Panama-Pacific International Exposition. Clearly, at least two different sizes with identical designs were manufactured. Although the details of the manufacture and distribution are unknown to us, it's not unlikely that Farran Zerbe was involved, as he operated the numismatic concession at the Panama-Pacific Exposition. Examples of these spoons are of great historical importance and the few known are ardently sought by collectors of pioneer gold coins and associated items.
