Anthracite has a carbon content above 90% and is also called Kilkenny coal or craw coal.
- The United States of America is the top country by reserves of anthracite and bituminous coal in the world.
- As of 2019, reserves of anthracite and bituminous coal in the United States of America were 219,534 million tons that account for 29.75% of the world's reserves of anthracite and bituminous coal.

- The world's total reserves of anthracite and bituminous coal were estimated at 737,853 million tons in 2019.
There are four types of coal-
Anthracite- has carbon content above 90% and very little volatile matter. It is the hardest and best quality of coal.
Bituminous has a carbon content of 40-80% and has a very high calorific value with volatile content of 15-40%.
Lignite- It is brown coal with 40-55% carbon and it undergoes spontaneous combustion.
Peat- It is the first stage of transformation and contains less than 40-50% carbon content.
