    i guessing here but could you mould the coin with a over pour flange then pour the metal in the open faced mould and then press the top of the mould over that?

    For what your suggesting the lost-wax process is best as you can attach several sprue's to your coin as you both want to be able to pour and vent to allow the air out as you pour the hot metal in , filing and trimming once cold with a fine Dremmel works best for me , I've made a lot of replica medals this way.

    For what you want to do - lost cast wax is the best and most effective to use, I've produced dubloons and other items medals in exactly the same way

    I have a friend that does those. He uses a sand mold and makes a small trench to pour the metal into.
