The Bronze Indian Head Cent was the second composition used for the Indian Cent series, the prior composition used copper-nickel. The new bronze composition was lighter and easier to strike. It was composed predominantly of copper with a mixture of tin and zinc. The other aspects of the Indian Cent composition were also changed slightly, resulting in slightly smaller diameter and thickness for the bronze coins. This composition was used during 1864 along side the copper-nickel composition, and for all subsequent years of the series. The same bronze composition was also used for the Lincoln Cent series almost uninterrupted until the replacement with a zinc based composition during 1982.

The Copper Indian Head Cent was the first composition of the Indian Cent series. The composition was actually composed of 88% copper and 12% nickel, the same composition used for the prior Flying Eagle Cents. The composition was used for the first five years of the new Indian Head Cent series before changing to the bronze composition which would remain in use for nearly one hundred years. The composition was changed since the copper-nickel based version proved to be hard and difficult to strike.

Special 90% silver versions of each of the 50 State Quarters were produced by the US Mint and sold to collectors. The US Mint had been making a special 90% silver proof set since 1992. This continued in 1999, when the State Quarters series began. Each Silver State Quarter was included as part of the annual silver proof set. Later in the series, a separate Silver Proof State Quarters Set was issued. The coin specifications of the silver state quarters match pre-1965 circulating silver quarter dollar composition.

The 50 State Quarters series was created to issue circulating commemorative quarter dollar coins for each state in the order they joined the Union. This ambitious ten year program is often credited with bringing new life to the hobby of coin collecting and inspiring interest in collecting coins from pocket change. The obverse of the State Quarters used a modified version of the obverse from the prior Washington Quarters series. The reverse featured a design which highlighted the unique aspects of the state being honored. The series began by honoring Delaware in 1999 and concluded with Hawaii in 2009.
