1940 Mercury Dime PF-67 NGC

---

In 1940, the Philadelphia Mint produced a remarkably small run of proof coinage, striking only 11,827 of these ten-cent pieces. Unlike standard circulating currency, these proof issues were crafted with meticulous care, resulting in sharp details and mirror-like surfaces. This particular coin has survived in an extraordinary state of preservation, receiving a certified grade of Proof 67 (PF-67). The obverse features the iconic winged Liberty head design, which is accompanied by the inscriptions "IN GOD WE TRUST" and the date "1940". Because it was struck at the Philadelphia Mint, the coin bears no mint mark. On the reverse, the design elements are framed by the traditional inscriptions "UNITED STATES OF AMERICA", "ONE DIME", and the Latin motto "E PLURIBUS UNUM". Struck in 90 percent silver, this coin contains 0.0715 troy ounces of precious metal. Its high-grade proof finish highlights the intricate details of the design, offering a window into the refined minting techniques of the pre-World War II era.
