The term "Wheat Penny" refers to a one-cent coin produced by the United States Mint from 1909 to 1958. It features an image of two wheat stalks on the reverse side, which is where it gets its name. The obverse side displays a portrait of Abraham Lincoln, making it a popular collectible among numismatists. Wheat Pennies are made primarily of copper, and their design was created by Victor David Brenner. Over the years, various mint marks indicate where the coins were produced, such as Philadelphia, Denver, and San Francisco. These coins are often sought after by collectors for their historical significance and unique designs.
