The year 1950 marks the first striking of proof coins in seven years, with the long hiatus due to the United States Mint focusing its efforts on making enough business-strike coinage to feed a hungry wartime economy and to make medals and other special pieces for World War II military personnel and their families. 1950 proof Lincoln cents aren't very scarce, though individuals buying these coins would be served best by purchasing pieces with minimal spots, even color, and nice overall eye appeal. Cameo specimens are especially desirable and strong worth premiums.
