Hard to say from the pictures, but comparing to https://collections.museumsvictoria.com.au/items/57841, there might be a bit more detail in the King's hair and area under his eye, and on the reverse the left arm of the centre cross almost touches the bottom arch on the pattern but is well clear on the standard.
Both reverses have 180 denticles and both obverses have 183 denticles by my count.
Are there any better images?
