Peace Dollars were created as a way to commemorate the restoration of peace following the end of World War I. Rather than being issued for a single year, the series continued for a number of years, as three United States Mint facilities struck silver dollars in relatively large quantities. Mintages for the series occur at two extremes with large numbers struck early in the series and low mintages and a significant key date towards the end of the series.
The Barber Dimes remain a series that is somewhat overlooked by collectors. During the 25 year span when the series was issued, there were numerous coins with lower mintages. Since these were not saved in any quantity, high mint state graded examples are extremely elusive. Although these coins carry premiums, they are low in comparison to coins of comparable rarity from other more popular series.
As one of the most popular series for collectors, the mintage figures for the Buffalo Nickel deserve some attention. As opposed to the previous two series for the denomination, there are no issues struck with prohibitively low mintages. The factor in making many issues of the series scarce was the impact of circulation, which wore away the identifying date on many coins.
The mintages of the Capped Bust Half Dime are well above the levels experienced for earlier issues of the denomination. This makes completion of a full set an achievable task for most collectors. The coin series carried a design based on the work of John Reich, but modified by John Kneass. The same basic design was used for the silver coinage of the era.

In all but a few cases, the mintages for the Liberty Head Nickel occurred in relatively high numbers. Most issues of the series with the exception of three remain relatively available for collectors. This is a contrast to the previous Shield Nickels, which saw mintage levels much more varied, including several years where coins were struck only in proof format.
