Ron Guth: The 1850-O Half Dime is not quite common but also not quite scarce -- except in Mint State. There, the most frequently-seen grade is MS62 and the best examples are MS66 (where two PCGS-graded examples are known). Many 1850-O Half Dimes are softly struck on the high points and the denticles, and some examples show clashmarks where the dies banged into each other without a planchet to separate them. The luster is usually frosty white, with a rich, satiny appearance.
