The three-cent coin, also known as the "trime," was minted in the United States from 1851 to 1889. It was available in both silver and nickel varieties and was introduced to facilitate commerce, particularly in the era of postal services. Patterns and trial coins for the three-cent denomination were created as early as 1870 in Philadelphia to evaluate new designs and materials prior to mass production. These patterns are considered highly collectible due to their limited mintage and historical significance.
