1999 Australian 1999 Ten Cent

Hi Nancy, the three nines on the top coin are noticeably different, is this just camera angle?
The tails appear to curl at a wider angle from acute to obtuse. My guess is from about 40 degrees to about 55 degrees. It can be seen in the picture of the dates you provide also, but less obviously.
On the first coin the tails curl in sequence from obtuse, average to acute.
On the second coin the 9's appear to be 2 of the acute type and one of the obtuse. [no middle]
Surely it is just the camera angle though. Or am I just mad?

I have found 2 1999 small head tens and the 9 of the 19 appears to be a slightly different style to the 99 of the year. The 9's of the 99 have a slighly more acute angle to the curl, but this is making a very fine distinction. You can see this in Nancy's date comparison if you look hard enough.
It is like back in the days of hand punched dates where they had a universal 19 and just updated the year, I wonder if they did modify an old die. Seems unlikely to me.

@Mr.Tan what mean is close to rim not included in photo. But take alook of both coins it seems they are differrent between them on ELIZABETH II, one is far and one is middle.

If is true there three variety for this year?

My God Nancy you never fail to deliver. Hope the large heads turn out to be valuable for you.

I only see a small and medium head in these pictures NO LARGE HEAD. Yes it does exist and it is very rare..!

The other side of the coin (AUSTRALIA) seems to show a uniform distance though. Some of the 1999 coins have a double struck rim which makes it difficult to work out what you have.
I'm only aware of two varieties for the 10c.

jerry do you have a comparison photo of the small, medium and large heads?

Is there a medium head?

Really? Which dealer?
I did sort some 1999 $1 coins recently and the medium/large head difference isn't an easy one to pick.
