50 Dollars

<< >>
Kellogg & Co. was one of the last private coiners to appear in San Francisco, but its double eagles were well made and well engraved. One of those responsible for the artwork was Ferdinand Gruner, another Central European emigre who may have also been responsible for some of the fractional gold coinage of the decade of the 1850s.
Kellogg & Co. was an offshoot of a larger firm, Moffat & Co. John Glover Kellogg had served as Moffat's cashier, while the other principal, G. F. Richter, had been its assayer.
Perhaps emboldened by public acceptance of their twenty-dollar coins, Kellogg & Co. put plans into motion to produce a fifty-dollar piece. Eleven coins, all proofs, survive to bear testimony to this idea. But no business strikes resulted, even though a competitor, Wass, Molitor & Co., did succeed in circulating such pieces during that same year.
