The histogram of copper content in all West Virginia coal beds shows a slightly skewed near-normal distribution with a mean of 20.40 ppm (± 19.79 ppm) on a whole coal basis with a maximum Cu content of 275.4 ppm in a bench of the No. 5 Block coal.  Copper did not correlate with ash yield, correlated moderately with lead (Pb), and poorly with europium (Eu), silver (Ag), tellurium (Te), cerium (Ce) and lithium (Li).
