For 1830, the Mint recorded 4,764,800 half dollars coined. Among these are 23 different varieties from 15 obverse and 20 reverse dies. One variety, O-114 with a Large Letters reverse, remains listed as Rarity-6. In 1970, Al Overton gave this a Rarity-8 rating. Two other varieties are considered scarce. Russ Logan collected 31 examples of this date representing all 23 die varieties. FIFTY CENTS HORALF A DOLLAR. JRCS Member Donald Gunnet developed a keen interest in edge dies for the lettered edge half dollars. In Volume 2, Issue 2 of the Journal, he penned an article discussing the Mint's experimental edge dies of 1830. He identified five distinctly different lettered edge types for the half dollar coinage of 1830. His earlier research with Ivan Leaman specified 16 distinctly individual edge die combinations among these five types.
