The 1931-S Mercury dime saw a low production figure of only 1.8 million but is still widely available today thanks to collectors, cognizant of this coin's low mintage, saving this piece in large numbers. Examples are generally plentiful in uncirculated grades up through MS65 with many Full Bands survivors. 1931 was the last year of Mercury dime production, which took hiatus during 1932 and 1933 due to the economically devastating effects of the Great Depression.
