Hi I found this 2005 lewis and Clark nickel. It is gold or copper colored. I couldn't find anything online. Same size as a nickel, although it feels lighter and the "lip" is a tiny bit thicker.
@alan, first welcome to CCF. Second, as noted by @sap above, the surface toning on these coins is typically due to environmental or chemical exposure. Sometimes they are even aftermarket plated!

The nickel can turn yellow due to exposure to chlorine and sulfur. Look at the sides. If exposited to external agents you will have different color and nuances.
