No, coal is not a mineral because coal is made of dead plants.
Coal is classified as a sedimentary rock, specifically organic sedimentary rock, as it is formed from the accumulation and transformation of plant material over millions of years. Although it is a useful resource, it does not meet the criteria to be classified as a mineral, which typically requires it to be a naturally occurring, inorganic solid with a definite chemical composition and crystalline structure.
