P.S. The cloudy smudges are just photo reflections....the coins and the glass encasement look pristine.
High Relief.....Just noticed that the very concave and high relief nature of the Wedge-Tailed Eagle coin makes it much smaller than the much flatter non-high relief Snake coin. Check 'em out.......
Confirmed.....just using a tape measure to get a guestimate, the Wedge-Tailed Eagle is 50 mm in diameter, the Snake is about 65 mm across.
