Order of quality of coal:.

Peat, lignite, bitumen, anthracite (best coal as most carbon content due to its long duration under suppression).

Peat under goes less carbonisation as compared ton other types of coal. It contains about 27-40% of carbon content. And due to less pressure & temp effects on plant orign it is visible in peat.

Anthracite (hard coal) contain 92-98% carbon.
Bituminous (house hold coal) contain 60-80% carbon.
Lignite (soft coal) contain 30-40% carbon.
Peat - this is the most inferior quality of coal.
