The Three Cents coin, produced by the United States Mint, was issued in various forms between 1851 and 1889. This denomination was introduced primarily as a small change alternative during a time of rising prices. Patterns and trial coins, often experimental in nature, were created to test designs before full-scale production; an example includes those from 1881. The "N A" designation indicates that the coin may have a specific feature or characteristic recognized by numismatic authorities. Collectors often seek these coins due to their historical significance and limited mintage.
