Designed by William Kneass, the half dime had a composition of 89.24% silver and 10.76% copper.
The obverse design depicts an idealized head of Liberty facing left, her hair covered by a cloth cap with a band inscribed LIBERTY. Her neckline is draped with a gown, secured with a brooch at the shoulder. Seven stars are to the left and six to the right (13 stars were representative of the original 13 states of the Union).
The reverse design features an eagle with the shield on its breast, perched on a branch and holding arrows, with E PLURIBUS UNUM on a scroll above, and UNITED STATES OF AMERICA and 5 C. There are no mint marks as the Philadelphia mint was the only mint during that time period so there were was no need.
An interesting note, the capped bust half dime was the first half dime to actually carry a denomination (5C.). Prior to this series, there was denomination on this coin indicating it's value of 5 cents.
General Market Notes
The Capped Bust is readily available to most collectors and typically can be found in the collector grades of G to VF and are affordable for most collectors. Higher grades of XF to BU are more difficult to locate and their price premium is reflective of that.
For collectors on a small limited budget you will probably want to limit yourself to a grade of Good to Very Good.
There are no rarities in the series so any example will fit your collecting or investing needs.
