As for hitting coins in the air. I saw my dad do it with both revolver and rifle.
I practiced a few thousand times and was able to do it with hulled black walnuts thrown by myself with my left hand into the air and the rifle was a Crossman pellet rifle I had as a kid. I was about 14 or so. It took hundreds if not thousands of throws to hit the first one. After that I got better and better, and could hit more than 50 percent of the time. I am not saying I can do it now. I really don't know if I can or not, or how long it would take to get back in the groove. By the time I was 14, where we lived then it was not safe to fire actual firearms into the air. The hitting of 50 cent pieces and silver dollar with rifles and pistols by my father was done in a much more sparsely populated area when I was younger. So I have no actual practice hitting objects in the air with an actual firearm except a shotgun. I can sure do that. I have seen videos of many persons hitting small objects thrown into the air with pistols, rifles and even arrows.
