Anthracite coal is harder than Lignite.

Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
They are types of coal . Ligniote is a very soft coal , that can be converted into bitumin for road building. Anthracite is a very hard shiny coal , with very few impurities.
Lignite is the youngest and softest coal; bituminous is mid-grade coal, and anthracite is the hardest and hottest burning coal. Even brown coal.

Anthracite is the highest carbon coal, and therefore the most valuable.

wood-peat-lignite-subbituminous-bituminous-anthracite The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
Peat is decayed vegetation probably thousands of years old but which has not been converted to coal. Lignite is called brown coal, again vegetable matter that has not become true coal. Anthracite is a very pure form of coal much valued for steam engines.
