If a coin has certain gross physical features such that a rational agent who knows those features (but NOT any details about how the coin is thrown) is forced to assign a probability p to the coin landing on "heads", then it seems reasonable to me to speak of discovering an "objective chance" or "propensity" or whatever. These would be "emergent" in the non-buzzword sense. For example, if a coin has two headses, then I don't see how it's problematic to say the objective chance of heads is 1.
