The Kellogg Company of San Francisco produced privately minted gold coins in the mid-19th century, notably the Kellogg & Co. gold coins. One significant type is the $50 slug issued in 1855, which was made of gold mined during the California Gold Rush. These coins were larger and heavier than official U.S. gold coins. They are highly sought after by collectors due to their historical significance and limited production. The G 20 designation often refers to various grades and classifications used in the evaluation of these collectible coins.
