The Rix Dollar was not a locally produced crude coin. It was manufactured in England and the examples that I have seen or owned always matched the English coinage in terms of crisp strike with no field irregularities.
This does NOT look like a genuine strike.
Perhaps it may have been mounted as jewelry but the level of field damage is atypical for even that use. Perhaps it started as a replica intended for jewelry. It really looks cast to me.
