Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
The rock you are referring to is anthracite coal, which is a type of metamorphic rock formed from coal with a high carbon content. Anthracite coal burns with a high heat and produces little smoke due to its high carbon content and low volatile matter.
Coal when subject to mild metamorphism turns into Anthracite, in which the carbon content is between 92% and 98%. If squeezed and heated still further, the coal will transform into graphite and of cause if the taken to extremes diamond will be produced, but that would require the coal to be taken deep into the earth's mantle.
Anthracite is a very hard rock that burns with high heat and little smoke. It is a metamorphic rock formed from coal through intense pressure and heat. It is known for its efficiency as a fuel source due to its high carbon content.
Anthracite coal is classified as a metamorphic rock. I've included two wikipedia links on this subject.

this would be organic sedimentary
Anthracite coal is a type of metamorphic rock that is formed from the compression of plant material over millions of years. It has a high carbon content and a lustrous appearance, making it a valuable source of energy.

No. Anthracite coal is a metamorphic rock.
Bituminous coal is sedimentary! Bituminous coal is sedimentary!
The coal variety anthracite is a metamorphic rock.
Anthracite coal is considered metamorphic. All other types are sedimentary.
