1934 50C Maryland MS66 NGC. Cecil Calvert, responsible for the eponymous Lord Baltimore coinage, is depicted on the obverse of the 1934 Maryland Tercentenary half dollar. The state arms grace the reverse. The authorized production of 25,000 pieces was distributed in full, plus 15 coins for assay.

1928 50C Hawaiian -- Obverse Improperly Cleaned -- NGC Details. Unc. Hawaiian commemorative half dollars were struck in June 1928. The mintage of 10,008 coins included eight assay pieces and 50 sandblast proofs. Coins went on sale in early October of that year, with a sellout following soon-after. The issue's popularity endures, mainly because of its ultra-low mintage. This piece maintains the sharpness of an Uncirculated coin, but an inoffensive obverse cleaning prevents a numeric assessment. Just a few small bag marks are seen, and each side showcases pale golden-brown tones. Ex: Eric P. Newman Numismatic Education Society.

1927 50C Vermont MS64 NGC. Although the French had set up forts in Montreal and Quebec City by the early 1600s, a few hundred miles away from Vermont, there were no permanent colonies established in the Green Mountain state before 1724. Even at that time, ownership of the territory was disputed between New Hampshire and New York states. In 1777, Vermont finally gained its independence, an event commemorated by these half dollars. The surfaces of this near-Gem example feature frosty luster beneath a translucent veil of pale gold toning. Reed marks on Allen's cheek and below the catamount define the grade. Ex: Eric P. Newman Numismatic Education Society.
