Sounds like the very epitome of a quantum superposition:
"Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured"...
Except for the very inconvenient truth that, in Reality, a coin continues "to be in multiple states at the same time..." even after it has been measured...
If the two astronauts had video cameras mounted on their helmets, transmitting video images to each other, they would both see the entire superposition, continuously, without it ever undergoing "collapse", into just one state or the other...
But how can such coins possibly exist at all? After all, the entire physics world has assured everyone, that superpositions like that, only occur in the quantum realm, not the classical realm.
"Something is rotten in the state of Denmark", in Copenhagen in particular, and in every other misbegotten interpretation of Quantum Reality.
