David Akers (1975/88): The 1851 is more rare than one would naturally expect from the fairly high mintage figure. While not as rare as the 1849 or 1850, it is comparable to the 1848 and more rare than the Philadelphia issues from 1843 to 1847. The date on this and the mintmarked 1851 Half Eagles is huge, taking up the entire space between the bust and the rim. Many specimens have an attractive greenish-gold color as do other gold denominations of this date. Despite its current "common date" status, the 1851 is very difficult to obtain in strictly uncirculated condition.
