Ron Guth: The mintage of the 1841-O Half Dime is identical to that of the 1842, but it is considerably rarer than the mintage might suggest and the 1841-O is always priced much higher than the 1842. Uncirculated examples are very scarce, bordering on rare, but there is a lone standout in PCGS MS67+ that is more than two points higher than the nearest competitor.
The overall strike characteristics for this date are normal to above-average for a New Orleans mint product, but on some examples, the dies had remained in place so long that they became clashed, cracked and the surfaces took on a pebbly appearance (these characteristics can be seen on the MS67+ example pictured above).
