There are some sites that can give you a better idea, but coal looks like coal. Anthracite is very hard for coal and it burns very clean. Since coal is very brittle you could break off a small piece and burn a piece on an outside grill and see if it burns pretty cleanly, like not a bunch of smoke.

Actually picture is very blurry and can't indicate anything based on the poor quality.
