1974 Urraca Republica De Panama Un Centesimo

It is a 1 centesimo from Panama. "Urraca" is the name of the fellow on the obverse; he was a native American tribal chief who led the resistance against the Spanish invasion of Panama.

The Panamanian currency unit, the balboa, was on par with the US dollar at the time your coin was struck, so it is the equivalent of a US cent. You'd probably pay only a few cents for one in typical condition from a coin dealer. As you have discovered, they still sometimes turn up in change in the US.

Great find ...
