This is a 5-cent coin issued by the United States in AD 1964, commonly known as the “Jefferson Nickel.” The coin is struck in cupronickel.

The obverse of the coin features a left-facing portrait of Thomas Jefferson, the third president of the United States. To the left of the portrait is the inscription of the U.S. motto, “IN GOD WE TRUST,” while on the right is “LIBERTY★1964,” representing the nation’s emphasis on the spirit of liberty and the year of issuance.

The reverse of the coin features a relief depiction of Monticello, the historic estate of Thomas Jefferson. Below the image appears the estate’s name, “MONTICELLO,” while to the right of the building is the mintmark “D,” indicating that the coin was struck at the Denver Mint. Along the upper edge is the Latin motto “E PLURIBUS UNUM,” meaning “Out of Many, One.” At the lower edge, two inscriptions appear: the denomination “FIVE CENTS” and the full name of the country, “UNITED STATES OF AMERICA.”

In AD 1938, the U.S. government introduced a new design for the Jefferson nickel, replacing the previous Buffalo nickel. However, following the attack on Pearl Harbour in AD 1941, which led to the U.S. entering World War II, the government began rationing metals for the war effort. Nickel, a critical material for producing tanks and aircraft, was especially in demand. As a result, in October AD 1942, the composition of the nickel was adjusted to 56% copper, 35% silver, and 9% manganese. This wartime nickel was produced until the end of the war in AD 1945.

這是一枚公元1964年，美國發行的面額5美分硬幣，俗稱為「傑佛遜五美分」，材質為白銅。

錢幣正面為美國第三任總統：湯瑪斯·傑佛遜左臉肖像，左側鐫刻美國格言「IN GOD WE TRUST」(我們信仰上帝)，右側則是「LIBERTY★1964」即美國強調的自由精神和發行年份。

錢幣背面為傑佛遜故居「蒙蒂塞洛」浮雕，下方為故居的英文名稱「MONTICELLO」，故居右側的「D」代表這枚錢幣由丹佛鑄幣局鑄造。錢幣上緣為拉丁文格言「E PLURIBUS UNUM」，即「合眾為一」。下緣有兩道大小不一的銘文，分別是面額五美分「FIVE CENTS」和完整的美國國名「UNITED STATES OF AMERICA」(美利堅合眾國)。

公元1938年，美國政府推出新版的傑佛遜五美分取代舊有的野牛設計。然而隨著公元1941年，美國於珍珠港遭到偷襲正式捲入世界大戰，政府開始對於金屬進行戰備管制，尤其鑄造五美分需要的鎳，為生產戰車和飛機的重要原料。因此於公元1942年10月，成分調整為：銅56%、銀35%和錳9%的戰時五美分投入量產，直到公元1945年戰爭結束為止。
