The coin, with a low mintage of just 100,000 examples, is basically an ingot of pure. Weight is good for the form at about 4.7 grams on my portable digital scale - around 1.24 grams of that being the pure gold Koala coin. Condition is quite good though not absolutely pristine perfect with an aura of time and some typical evidence of previous service in the cause of adornment to the gold surfaces - this was obviously someone's favorite, just as it might be yours. A look at the pics should give a good idea of appearance and condition.
Ring size is about 5 1/4 or possibly 5 1/2 on my jeweler's ring mandrel (the bottom edge of the shank reaches between those lines on the mandrel). I'm not sure what else to say, so there you are.
