The Seated Liberty Half Dimes represented the last of the silver half dime denomination. The five cent nickel had been introduced in 1866 with the Shield Nickel, and less than ten years later, the last silver half dimes were struck in 1873. During the course of the final half dime series, the silver content was reduced.
The obverse of the Liberty Seated Half Dime features the allegorical figure Liberty seated on a rock, as the name suggests, at various points in the series, the surrounding fields are empty, contain thirteen stars, or contain the motto “United States of America.” The reverse contains a wreath with the denomination spelled out in the center. This wreath was changed significantly later in the series.
The original composition consisted of 90% silver and 10% copper with a weight of 1.34 grams. In 1853, the weight of the coins was changed to 1.24 grams. To indicate the coins with the new composition, arrows were placed to each side of the date for coins with the new measure.

The Washington Quarter was introduced in 1932, replacing the Standing Liberty Quarter, which was minted for the last time in 1930. The new series was originally intended to be issued for only one year to celebrate George Washington’s bicentennial. The popularity of the design led to the continued use until 1998.
Washington Quarters were issued with a composition of 90% silver for the beginning of the series from 1932 to 1964. During this time, the coins were produced for circulation at the Philadelphia, Denver, and San Francisco Mints. All proof coins of this era were produced at Philadelphia. From 1992 to 1998, the US Mint also produced silver quarters of the same specifications for sale to collectors in special sets. These coins were all minted at San Francisco.

The Classic Head Half Cent was the third design used for the half cent denomination. It was used from the introduction in 1809 through 1836, the date of a rare proof only issue. John Reich was the designer of the coin which features a head of Liberty wearing a headband with the word “Liberty” on the obverse and a wreath of laurel leaves encircling the denomination on the reverse. The Classic Head Half Cent would have the same coin specifications as the previous Draped Bust design, although a refinement of minting techniques would make the actual specifications of most coins closer to the stands.
As with all small denomination coins of the era, production took place at the Philadelphia Mint only. Despite the span of the series, sporadic production reduces the number of dates in the series to just thirteen dates, including two struck in proof only version.
