All coal is metamorphic and sedimentary rock. When coal forms it is made out of ancient organic material, and over a long period of time the coal is buried under sediments and water. (That part makes it sedimentary) Over time in order to make the coal we know today heat and pressure (That is what makes it metamorphic) makes the organic material turn hard and solid to become coal.
