What is a 2009 penny worth with man fishing on back?

The 2009 penny that you are describing appears to be the first issue of the Lincoln "Bicentennial Commemorative" pennies series with the reverse displaying a fisherman standing next to the word "Liberty". While some commemorative US pennies can indeed fetch higher prices due to their desirability in mint condition, this particular series typically retains its face value as it was widely minted and is not rare. Therefore, a 2009 penny with a fisherman on the back is still worth one cent.
