Bituminous Coal exists in the geological area known as The Pittsburgh Coal Seam-- an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Though mined since the days of Native American Indians, and heavily mined since 1800, it is estimated there is still enough coal in this large seam to last millions of years. Bituminous coal is a soft coal and was well-suited to burning in factories and homes, and thus, held more demand and higher price.

The main difference is the amount of carbon. Anthracite is harder and contains more carbon. Bituminous coal is a sedimentary rock and anthracite coal is actually a metamorphic rock that has undergone tremendous pressures, usually from mountain building events.
Gold, silver, and coal have been mined in the past and are still being mined today. However, new technologies and increasing demand have also led to the mining of rare earth elements, lithium, and copper in more recent times.

Depends on where it came from. If this is mined coal( which it usually is) it's nonrenewable. If it is coal made from dead wood, this is renewable. We can always grow more trees.
