1854

The 1854 three-cent silver introduced the Type II design and a new composition. The Mint modified Longacre's obverse by adding three outlines around the central star (Type II is sometimes called the "Three Line" variety as a result), giving the design more visual weight. The reverse gained an olive branch above the Roman numeral III and a bundle of arrows below, traditional symbols of peace and war. Most significantly, the composition changed from 75% silver to the standard 90% silver used on other American silver coinage, while the weight dropped from 0.80 grams to 0.75 grams. The net effect was slightly more silver content in a lighter coin: 0.0217 troy ounces of silver versus 0.0193 ounces in the Type I version.

The composition change was driven by the California Gold Rush and its aftermath. Gold had become cheap relative to silver during the early 1850s, which meant silver coins were being melted or exported because they were worth more than face value. The three-cent silver, with its initially reduced silver content, had been partially insulated from this pressure. Raising the silver content made it consistent with other coins but also made it vulnerable to the same melting pressure. Mintage dropped sharply as a result. The 1854 saw only 671,000 coins produced, a small fraction of the previous year's output.

The semi-key status reflects the low mintage and the transition to Type II. The 1854 is the scarcest common-date trime in circulated grades, and collectors pursuing a complete date set face the 1854 as an early challenge. The new design's three-line star outlines are a distinctive visual marker; comparing a Type I to a Type II shows immediately why the Mint made the change. The Type I star floats alone; the Type II star has depth and substance.
