I do this for a living. This mold won't work. The material won't flow into the raised areas...only the cavities. You will end up with rings, and nothing in the middle.

    I get what you mean, but did you consider they might pour enough molten metal into the mold so it overflows each cavity along the coin tree, with the whole patterned area becoming one side of the coin?

    That doesn't change the fact that cavities are where the material flows. On this mold, the cavities are all the places around the coin.

    I suspect this side of the mold is flush with the face of the coin and the other side is recessed to the depth of the coin. That would give the depth of the coin for metal to flow and still make this a workable partial mold.

    Or you're completely right and this is an unworkable mold.

    🤷‍♂️
