The 1919 penny, also known as the Lincoln cent, is a common coin and its value is determined by its condition, rarity, and numismatic value. In general, a 1919 penny in average circulated condition is worth a few cents. However, if it is in mint condition or has special characteristics such as errors or varieties, its value can be much higher. For example, a 1919-D penny in uncirculated condition can be worth several hundred dollars. It's always a good idea to consult with coin experts or visit reputable coin dealers to assess the value of a specific 1919 penny.
