it is indeed a compound, but its more of a mixture actually.
Sulfur is an element.
Sulfur powder is an elemental substance, not a compound. A compound is a substance made up of two or more different elements chemically bonded together, while sulfur is a single element with atoms of the same type.
Sulfur powder, which is composed of pure sulfur atoms, is an element. Elements are substances made up of only one type of atom that cannot be broken down into simpler substances by chemical reactions.
Sulfur powder is not an element; it is a compound made up of sulfur atoms. Sulfur itself is an element on the periodic table, identified by the atomic number 16. In its elemental form, sulfur exists as yellow crystals.

It's a compound. If it was all one element it would all change the same way into the same thing. Since it's a compound, the molecules break up and the groups of atoms react differently to the heating (one becomes a gas, the other remains solid).
The coin was likely made of copper, which is an element commonly used for making coins. When heated, copper reacts with oxygen in the air to form copper oxide, which is a black compound.
