CU-5c-1940S-01 Cud

Description

Listed by Cuds on Coins as CU-5c-1940S-01, this 1940 San Francisco Jefferson Nickel features a cud error from the early years of the series. The Jefferson Nickel debuted in 1938, designed by Felix Schlag after winning a public competition to replace the Buffalo Nickel. By 1940, the series was only in its third year of production, making cud errors from this period particularly interesting to collectors who appreciate both the die variety and the historical context. San Francisco Mint production of Jefferson Nickels during 1940 was modest compared to Philadelphia, adding a layer of relative scarcity. A cud forms when a section of the die rim breaks away completely, and the resulting gap in the die surface allows metal to flow into the void during striking. The raised, featureless mass that appears on the finished coin contrasts sharply with the surrounding design detail. Cuds on early-date Jefferson Nickels are less frequently encountered than those from later high-mintage years, making documented examples like this one valued reference pieces for error specialists.
