A 2000 wheat penny is worth its face value of one cent, as it was produced after the U.S. Mint stopped producing wheat pennies in 1958. However, if you have a 2000 penny with an error or in uncirculated condition, it might be worth a bit more to collectors. Typically, standard 2000 pennies are not considered valuable.
