The 1850-O Quarter is one of the more common dates of the pre-1853 era, but it is every bit as scarce as many of the other dates in Mint State. Most Uncirculated examples are low-end, usually MS63 or less, and only one or two examples are known in MS64 and above.
The typical 1850-O Quarter is well-struck in the centers, but often shows weak denticles and stars.
