1854 Kellogg & Co. $20. K-1b. Rarity-5. Short Arrows. AU Details--Cleaned (NGC).This is a rather appealing example for the assigned grade, both sides sharply to fully defined over most features and dressed in vivid golden-orange patina. Light hairlining and a curious matte-like texture explain the NGC qualifier, although there are few sizable marks for an example of this heavily circulated issue. Delivering some 300,000 twenty-dollar gold pieces from February 9, 1854 through 1855, the firm of Kellogg & Co. helped bridge the gap when Californians were awaiting the official opening of the San Francisco Mint. As such, it ranks with Moffat & Co. and the United States Assay Office of Gold as one of the most important private minting establishments of the California Gold Rush.
