Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
Anthracite coal is a type of metamorphic rock. It forms from the transformation of bituminous coal under increased temperature and pressure over time.

Anthracite is a metamorphic rock commonly called coal ,whose protolith or parent rock is bituminous coal.
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.
Anthracite coal is a metamorphic coal that has a higher luster than any sedimentary coals. It also has the highest carbon content. Otherwise it is very similar to sedimentary coal. Diamond is commonly thought to be the metamorphism of coal but this is largely untrue as the immense majority (near 100%) of diamonds have nothing to do with coal.

Anthracite coal, a type of coal with a high carbon content and low impurities, can turn into metamorphic rock called graphite under high heat and pressure. Graphite is a soft, crystalline form of carbon that is a good conductor of electricity.
