Heritage auctions on the history of these slugs: Few issues are as evocative of the romantic gold Rush era as the massive fifty dollar slugs produced by Moffat & Company in the early 1850s. The scarce K-11 fifties were struck in the first few months of 1852, shortly before John Little Moffat retired to return to the gold fields. Moffat & Company held the government contract to produce gold coinage in California and the fifty-dollar slugs were very useful for settling large transactions in the economy of the region, where paper money did not circulate. Of course, they were less useful for smaller day-to-day transactions. The company was reorganized after Moffat left as the U.S. Assay Office of Gold, and the government contract was continued. Moffat's partners, Curtis, Perry, and Ward, continued in their managerial roles and Augustus Humbert continued as assayer. Many of the K-11 fifty-dollar pieces were melted and reissued under the auspices of the new company, making the issue quite scarce today.
