Pics Of Two 1919 Australian Pennys

Yup, those are nice clear pics, and it looks to me like you've got two different varieties there, but sadly neither of them are the valuable one.

Can you spot the difference? I sure can't, unless I see a picture blown up that big.

On the reverse of the top coin, below the word "PENNY", there's a tiny dot in between the lower scrolly-thing and the circle of beads. It's very faint, but I can see it in the picture there. The lower coin doesn't have this dot. The scarce variety for this date has the lower dot, as well as a similar tiny dot above the upper scroll.

I'm not entirely sure what the dots mean; they're not "mintmarks" in the normal sense. I think they were some kind of die control marks used in the Sydney and Melbourne mints.

Sap...thanks! Interesting little dot. I'm sure I would never, ever have seen that.
