I concur with Wayne here. Unless another metal was present, coal would not work.
Depending on the type of coal, and its mineral and/or metal composition, would
determine if it worked or not.

The receiver was a crystal set. They tried a rusty razor blade as a
detector which did not work.......but then tried a piece of coke (NOT
Cocaine,  partly burnt coal) which worked.

Coke is the product from burning coal, if I recall. Coal, like some other
sedimentary minerals, often has metallic impurities like lead and arsenic.
It is conceivable that in the burning and cooling process some such
metallics crystalized in compounds that would work. Galena might even have
been formed, since sulphur is also often present in coal and galena is a
lead sulfide.
