Like Mark Twain, I am happy to be able to answer this question without any hesitation: I don’t know.
But I’m sceptical that we can observe superposition of quantum states on that kind of macroscopic scale.
Also, the universe may be a fixed 4-dimensional shape, part of which includes the past and future states of you and the coin, and the illusion of different possible futures for you or the coin is just that. I have no evidence for or against this, though.
