The penny dated between 1909-1955 have small errors which make them the most valuable

In light of President Donald Trump’s desire to eliminate the penny, it’s noteworthy that one of the most significant coins globally is the Lincoln Wheat Penny, valued at an impressive $121 million.
This penny holds historical importance, having been introduced in 1909 to commemorate President Abraham Lincoln’s 100th birthday, featuring his profile on one side and wheat stalks on the other.
Production continued until 1958, when the Lincoln Memorial penny replaced it.
The most valuable Lincoln Wheat Pennies are the year 1909-S, 1914-D, 1943 (copper), and 1955 (double die error), have a small letter under the year, and could have misprints. The penny remains in circulation for now, meaning anyone could have it.

The lowly penny, the forgotten mainstay of coin jars and car cupholders everywhere, may soon be no more.
President Donald Trump announced Sunday that he’s ordered his administration to cease production of the 1-cent coin, the buying power long past its prime.
Advocates for ditching the penny cite its high production cost — currently almost 4 cents per penny, according to the U.S. Mint — and limited utility. Fans of the penny cite its usefulness in charity drives and relative bargain in production costs compared with the nickel, which costs almost 14 cents to mint.
Trump’s surprise order comes after decades of unsuccessful efforts to pitch the penny.
“Only tradition explains our stubborn attachment to the penny. But sometimes traditions get ridiculous,” the Farmers’ Almanac said in its 1989 edition.

It depends on what you mean by circulation.
